Business Development (Medical) / Application Engineer, Murata Electronics

Silicon Integrated Passive Device (Si-IPD): an integration platform with high performance capacitors enabling high temperature operation exceeding 250°C.

Murata Silicon Technology is a disruptive technology based on unique 3D silicon structures that enable the integration of high-density capacitors (SiCap) using a semiconductor MOS process and multiple metal-insulator-metal (MIM) layer stacks. Several SiCaps can be integrated as an array on a single die, eventually combined with resistors and/or inductors on the same substrate, thereby implementing a monolithic RLC network or a Silicon Integrated Passive Device (SI-IPD). A Si-IPD can be seen as a full passive integration platform enabling numerous and advanced assembly scenarios ranging from Multiple-Chip-Modules to SIP. Whether with wirebonding or flip-chip, a Si-IPD can be used as an interposer to mount other elements (e.g larger passives, active dies, ASIC, crystal, saw filter, diodes...) and implement a complete functional system in a miniature module. Murata Silicon Technology is one of the fastest growing technologies as SiCaps exhibit very interesting properties that lead to advanced solutions and better performance in diverse applications: high temperature operation for Automotive and harsh environments such as soil drilling for oil & gas, high reliability and miniaturization for Medical implantable devices, high signal & power integrity for Networking (RF power, Broadband) and Communications. SiCaps effective capacitance is highly stable over time and over the complete operating ranges of temperature (-55°C to 250°C max spec), AC voltage/frequency and DC voltage bias. SiCaps can be mounted with wirebonding or soldering as there are multiple pad's metal finishing options available (e.g Alu, Au, NiAu, TiWAu, ENIG, Copper) eventually adding SAC305 or C4 bumps, or copper pillars. Wirebonding has been the main solution for high temp applications, but high temp joints are now possible thereby not limiting the maximum temperature anymore. This is a major advantage for SiCaps over other technologies as maximum operating temperature currently specified up to 250°C is yet to be explored by new designs beyond 300°C. Additionally, SiCaps are beneficial for signal integrity thanks to very low insertion losses (up to 110GHz) when used for AC coupling, or for power integrity thanks to very low ESL when used for supply line decoupling. Last but not least, SiCaps/Si-IPD can be thinned down to 100um, or even less depending on the required capacitance, thereby offering a solution without compromise to compact and height-constrained designs.

In this presentation, we will describe the SiCap trench technology, the capacitance density versus breakdown voltage trade-off that defines a process node, the electrical/mechanical/reliability benefits and advantages, the higher level of system integration it enables, and examples of SiCaps/Si-IPD designs while focusing on selected cases of automotive and high temperature applications. We will also review the process nodes currently in volume production and the roadmap of upcoming ones

All-in-one, wireless, stretchable hybrid bioelectronics for smart, connected, and ambulatory physiological monitoring

Commercially available health monitors rely on rigid electronic housing coupled with aggressive adhesives and conductive gels, causing discomfort and inducing skin damages. Also, research-level skin-wearable devices, while excelling in few aspects, fall short as concept-only presentations, due to the fundamental challenges in active wireless communication and integration as a single device platform. Here, we introduce the first demonstration of an all-in-one, wireless, stretchable hybrid electronics with key capabilities for real-time physiological monitoring, automatic detection of signal abnormality via a deep-learning, and a long-range wireless connectivity (up to 15 m). The strategic integration of thin-film electronic layers with hyperelastic elastomers allows the overall device to adhere and deform naturally with human body while maintaining the functionalities of the on-board electronics. The stretchable electrodes with optimized structures for intimate skin conformation are capable to generate clinical-grade ECG and accurate analysis for heart and respiratory rates while the motion sensor assesses physical activities. Implementation of convolutional neural networks for real-time physiological classifications demonstrates the feasibility for multi-faceted analysis with a high clinical relevance. Finally, in vivo demonstrations with animals and human subjects in various scenarios reveal the versatility of the device as both a health monitor and a viable research tool.

Wireless, battery-free, millimeter-scale UV dosimeters

Ultraviolet radiation (UV) has a dose-dependent consequence on the skin health. Overexposure to UV is the primary cause of skin cancers, the most common type of malignancy in the United States. Although quantitative monitoring of UV exposure is important, current technologies are confined to use in laboratories due to unfavorable properties in bulk, weight, and accuracy. Here, an optoelectronics design with fully-passive and continuous detection mechanism and wireless operation serve as a basis for highly accurate, battery-free, miniature dosimeters. The platform consists of a system-on-a-chip with near field communication, a radio frequency antenna, photodiodes, supercapacitors, and transistors. Applications of this dosimeter can allow consumers to modulate personal UV exposure during day-to-day activity and reduce risks of overexposure in order to prevent sunburns and skin cancers.

Process-Property Interactions for Additive Printed Electronics under Extended-Time Print Runs

Traditionally, the printed circuit assemblies have been fabricated through a combination of imaging and plating based subtractive processes involving use of photo-exposure followed by baths for plating and etching to form the needed circuitry on rigid and flexible laminates. Additive electronics is finding applications for fabrication of IoT sensors.  The emergence of a number of additive technologies poses an opportunity for the development of processes for manufacture of flexible substrates using mainstream additive processes, which are now commercially available.  Aerosol-Jet printing has shown the capability for printing lines and spaces below 10 µm in width.  The Aerosol-Jet system supports a wide variety of materials, including nanoparticle inks and screen-printing pastes, conductive polymers, insulators, adhesives, and even biological matter.  The adoption of additive manufacturing for high-volume commercial fabrication requires an understanding of the print consistency, electrical and mechanical properties.  Little literature exists that addresses the effect of varying sintering time and temperature on the shear strength and resistivity of the printed lines.  In this study, the effect of process parameters on the resultant line-consistency, mechanical and electrical properties has been studied.  Print process parameters studied include the sheath rate, mass flow rate, nozzle size, substrate temperature and chiller temperature.  Properties include resistance and shear load to failure of the printed electrical line as a function of varying sintering time and varying sintering temperature.  Aerosol-Jet machine has been used to print interconnects. Printed samples have been exposed to different sintering times and temperatures. The resistance and shear load to failure of the printed lines has been measured. The underlying physics of the resultant trend was then investigated using elemental analysis and SEM.  The effect of line-consistency drift over prolonged runtimes has been measured for up to 10-hours of runtime.  Printing process efficiency has been gauged a function of process capability index (Cpk) and process capability ratio (Cp).  Printed samples were studied offline using optical Profilometry to analyze the consistency within the line width, line height, line resistance and shear load to study the variance in the electrical and mechanical properties over time.

Additive Manufacturing: Innovating for Medical Ultrasound Probes

Two additive manufacturing processes developed at GE Research are applied to ultrasonic transducer arrays.  First digital micro-printing (DMP), comprising the deposition, patterning, and curing of transducer acoustic stack layers, expands the acoustic design pallet. Both piezoelectric(PZT) and acoustic matching layers with impedances ranging between 2-9 MRayls with thickness control of a few microns have been demonstrated. Second, aerosol-jet direct-write (DW) prints conductive traces for electrical connections between the acoustic stack and imager electronics.  DW provided design flexibility in depositing fine line (50-200 um), conductive traces over relatively complex substrate geometries. Moreover, these structures are more robust than earlier flex circuit alternatives.

Bio: Scott Smith has spent his career at GE Research mostly in ultrasound transducers.  Initially he developed high sensitivity phased arrays for echocardiography. Recent interests include matrix and electronic volumetric imaging arrays, adaptive acoustics, and additive probe fabrication methods.   Despite being trained as a physicist, he is a Fellow of the IEEE where he serves as Associate Editor of the Transactions on Ultrasonics Ferroelectrics and Frequency Control, and will serve as General Co-chair of the 2020 International Ultrasonics Symposium.   Throughout his career, he has been fortunate to work with, and learn from, teams of motivated and creative scientists and engineers.

New-Generation, Low-Temperature Lead-Free Solder for SMT Assembly

SAC305 is the major solder alloy after RoHS was adopted by the European Union. Since its melting temperature is relatively higher than eutectic SnPb alloy, the peak reflow temperature increases. This transformation in the assembly industry impacts the component requirement, the deformation probability (warpage) of a flat component is increased, which impacts the production yield. A lead-free, low-temperature SMT solder is needed to resolve this dilemma.

Low-temperature SMT assembly refers to the reflow process with peak temperature less than 180°C. The new process provides a few advantages like reducing energy consumption, reducing BGA component warpage during reflow and diminishing non-wetting open (NWO) and head-on-pillow (HoP) defects. The SnBi alloy is one of the candidates used in low-temperature SMT assembly.

There is several drawback of SnBi alloy. Its brittle characteristics will degrade the reliability of the assembly. Hot tearing is another joint defect impacting the reliability.

In-situ Synchrotron Characterization of Nanofiber Synthesis for Solid-state Battery Applications

Solid-state lithium batteries have been identified as the next-generation form of high performance energy storage due to their nonflammable solid-state electrolytes (SSEs) and high energy density. As compared to bulk ceramic SSEs, nanofiber SSEs have multiple advantages relative to device integration, charge carrier conductivity, and charging rate, which results from their nanocrystalline nature and long-range continuous conduction channels. In this presentation, synthesis of nanofiber electrolyte materials under in-situ synchrotron-based small angle X-ray scattering will be discussed, which shows significantly reduced development time and cycles.

The Importance of MEMS Cavity Gas Composition

MEMS are still occasionally packaged in large ceramic packages for custom applications, but most commercial MEMS are packaged in small multichip packages.  As MEMS are movable structures, most need a sealed hermetic environment for yield and reliability concerns.  This environment is provided by capping the structure in a controlled gas environment.  Large cavities can be gas composition tested with traditional RGA methods, yet small nanoliter sized cavities have problems with the traditional testing methods.  This talk will cover the various methods for testing gas composition in MEMS cavities over a volume size range.  Yield and reliability failure mechanisms will be shared when the gas composition is incorrect.  New packaging with in-situ sensors and getters will be shared.

 Knowledge Gaps and Challenges for Nanotechnology Commercialization and a Solution via Terahertz Camera-less Imaging Route

Nanomaterials will play a key role in the next generation of electronics including the high-density packaging and interconnects. However, progress in commercial utilization of nanomaterials requires deeper understanding of these materials and their interactions with other materials. For example, the most critical knowledge gaps and challenges hindering commercialization include measurements and standards for manufacturing, characterization of nanomaterials, interactions between nanomaterials and the bulk, dewatering and drying (when appropriate), management of interfacial properties, and environment, health, and safety (EHS) considerations.

The terms “measurement” and “characterization” are differentiated only by the extent of analysis. Measurement or Metrology is the basis for all characterization. “Measurement,” indicates the routine analytical work necessary for manufacturing and quality control, and for compliance with environmental, health, and safety (EHS) regulations. “Characterization,” on the other hand, is the detailed analysis to define the key properties of a given material and usually not done on a routine basis.

A modern characterization lab requires millions of dollars to procure necessary instruments. So, could there be a way to do all necessary measurements in a more comprehensive yet in a cost-effective way? The principal disadvantages of the existing methods are capital cost, length of time required for sample preparation and measurement (several hours to days), high level of technical expertise required, and high facility construction costs due to special environmental requirements for many of the instruments in terms of acoustic and mechanical vibrations, electromagnetic fields, etc.

In this talk, an alternative measurement technique is described in terms of terahertz camera-less imaging and spectroscopic route. A few practical examples are used to outline specific issues and their practical solutions.

Bio: Dr. Anis Rahman is an acclaimed scientist in the field of semiconductor and nanotechnology. He is a winner of many scientific awards including NASA Nanotech Brief’s “Nano-50” award twice; CLEO/Laser Focus World’s “Innovation award;” and “2015 MP Corrosion Innovation of the Year,” by the NACE.

Thermal benefit of power modules with organic insulation layer

The ever-increasing power density in power electronics results in ever higher temperatures of the semiconductors in power modules. This fact leads to a performance limitation of today's modules. The standard modules, which are available in the market, are not designed optimally from a thermal point of view due to the shear-sensitive Direct Copper Bonded Substrates (DBC) used in standard power modules. A sufficient thermal spread cannot be achieved.

As a consequence of the high fracture sensitivity the ceramic layers for electrical isolation in the DBC, such as aluminum oxide (Al2O3), cannot be designed thinner and the copper layers on which the semiconductors are contacted cannot be designed thicker. If this would be possible the thermal resistance of the overall structure could be reduced by the thinner insulation layer and the thermal spread could be increased by using thicker copper layers directly underneath the semiconductor. Then, the thermal spread would directly take place in the copper layer below the semiconductor instead of the base plate like in the current state of the art. This leads to a reduction of the semiconductor’s temperature and thus to an increased performance of the module.

Advanced Biocompatible Sensing Platforms

Sensors in biomedical applications monitoring critical chemical information (e.g., pH and glucose) and vital physical signs (e.g., temperature and ECG) are utilized with rigid electrodes and thus, limit intimate integration with our bodies that are soft, curved, stretched, and continuously evolving. The mismatch of mechanical properties between sensors and dynamic living biological systems causes tissue damage and/or induce the foreign body response, leading to inaccurate measurements. Additionally, unconformable contact of sensors on the body system impedes their function of the device in a biomedical and wearable health monitoring application. Therefore, my research has been focused on developing biosensors to enable quantitative analytical detection along with enhancing the biocompatibility of mechanical and chemical properties of devices. These advanced sensing systems hold great potential to improve human life and health indeed. Herein, I will present the development of biocompatible biosensors: (1) epidermal microfluidic sensor with wireless communication electronics for sweat monitoring, (2) ultrathin injectable temperature sensors for cardiac ablation monitoring; (3) porous sensors capable of natural convection of biofluids. Each sensing systems was specifically developed to eliminate profound mismatch in mechanical properties or to mimic an active biological system exploiting the role of a living system. These unique approaches in developing biomedical sensors bring significant advances in biomedical and mobile health applications.

Flexible Electronics and Smart Textiles for Medical Applications

Patient monitoring has been a focus in the development of smart textiles from the beginning. T-Shirts with different sensor functionalities have been developed over the years. Not many products have been brought to market successfully. Recently there is a trend to expand the area of application. E-Textiles but also flexible devices like patches are used in prophylaxis, diagnosis, monitoring, treatment and rehabilitation. These new devices are very specialized and optimized for different locations on the body. This specialization of the devices lead to new requirements regarding the materials and integration technologies – for textiles as well as flexible and stretchable modules.

Bio: Christine Kallmayer received a diploma in experimental physics at the University of Kaiserslautern in 1994. Since 1998 she is responsible for the group „System on Flex“ at Fraunhofer IZM. The main research areas are new technologies for flip chip integration on and in flex by soldering or adhesive bonding. Especially technologies for ultrathin chips are developed and investigated. The group is also developing new flexible substrate materials, e.g. based on thermoplastic polymers, together with optimized assembly technologies. A current research focus is on stretchable and conformable electronics based on textiles as well as elastomers.

Conductive Yarns and Fabrics for use as a Sensor Electrodes and Smart Wear Sensors

This presentation will give an overview about the new paradigm of electrodes and sensors for use in wearable devices. Advantages of textile electrodes are their ductility, flexibility, high conductivity and therefore their functionality for sensors and electrodes as well as surveillance of body signals such as EMG and ECG. A vital part of textile electrodes are conductive (silver or other metal compounds) yarns or fabrics integrated directly into the clothing. Through its direct implementation into the clothing (achieved via weaving, knitting, embroidery, etc.), the textile electrode guarantees an ideal body fit as well as enhancing patient compliance because it prevents intolerances of the patients resulting from the awkwardness of conventional electrodes. In addition, textile electrodes are washable, sterilize-able, re-usable, and can be applied to a wide variety of base materials. Applications of textile sensors are for example EMG, ECG, EEG as well as the measurement of skin resistance. Applications of textile actuators are for instance TENS, FES, and EMS.

Adding a new sensing dimension to soft electronics: from the skin to below the skin

Soft electronic devices that can acquire vital signs from the human body represent an important trend for healthcare. Combined strategies of materials design and advanced microfabrication allow the integration of a variety of components and devices on a stretchable platform, resulting in functional systems with minimal constraints on the human body. In this presentation, I will demonstrate a wearable multichannel patch that can sense a collection of signals from the human skin in a wireless mode. Additionally, integrating high-performance ultrasonic transducers on the stretchable platform adds a new third dimension to the detection range of conventional soft electronics. Ultrasound waves can penetrate the skin and noninvasively capture dynamic events in deep tissues, such as blood pressure and blood flow waveforms in central arteries and veins. This stretchable platform holds profound implications for a wide range of applications in consumer electronics, sports medicine, defense, and clinical practices.
