MEMS Design Innovations
MEMS product development often involves the co-design of MEMS devices, associated electronics, custom packaging and new fabrication processes requiring collaboration between domain experts--the “one product, one process, one package” dilemma. This session will focus on design for manufacturable MEMS based products and new trends in their design including design re-use and semi-custom design as well as new design techniques in fully custom designs. The increasing importance of system level design and software for MEMS-based products will also be highlighted.
The Changing Landscape of MEMS Manufacturing and Process Technologies
MEMS product development has often involved creation of new fabrication processes, fabrication sequences, and the use of new materials. Equipment manufacturers are providing new MEMS-specific equipment with enhanced capabilities and new materials are being utilized to enhance MEMS performance. In addition, traditional MEMS fabrication processes are being combined with new technologies such as 3D printing, meso-scale fabrication techniques, and nanotechnologies creating both great opportunities and great challenges for getting products to market in a timely, cost effective manner. This session will provide a look at the changing landscape of MEMS manufacturing and process development in the context of the “manufacturing renaissance” happening worldwide.
MEMS Packaging – Impact on Devices and Volumes
Electronics packages typically allow electrical connection while allowing the devices contained within to remain as isolated as possible from their environs. MEMS devices must interact with their surroundings, they are often subjected to direct contact with the environment, and usually must sense a particular variable without contamination from other potentially interfering inputs. Packages need to allow appropriate interaction with the measurand of interest, connect to power and signal I/Os, provide some isolation from undesired inputs, and create a test interface. The ideal package does all of the above and costs almost nothing. Low cost is achieved largely by exploiting existing high-volume technologies to the extent possible.
From another viewpoint, MEMS approaches have informed packaging efforts of traditional electronics. Stress isolation, deep trenching, wafer stacking, thermo-mechanical management techniques, and 2.5D and 3D package approaches have borrowed from the MEMS playbook.
This session will include speakers with insights into packaging of MEMS and the impact of MEMS on devices and their packaging at volume.
MEMS Device Testing Challenges
Testing of MEMS has been a traditional challenge as compared to CMOS devices. The need to measure a major physical input while eliminating minor inputs over temperature and with varying performance parameters has made this aspect of MEMS device production costly and difficult. The design of test systems follows closely the “one product, one test protocol, one test system” paradigm that is developed by the product company. Our speakers will address some of the issues and solutions that have been used in testing devices and which could be used in creating standardized testing of MEMS devices for high volume low cost applications in the future.
Several converging trends are transforming the entrepreneurial process for starting MEMS companies and transitioning MEMS devices into production and into the market. First, it is well-known that recent market set-backs have caused traditional VC funds to view any hardware start-ups with renewed scrutiny and skepticism. Hardware start-ups typically require large amounts of capital ($50-$100M) and many years (7-10), before getting close to a reasonable exit. This large investment in money and time is on top of the already inherently risky prospects for such a start-up being commercially successful. Secondly, MEMS is recognized, by investors, by foundries, and by large consumer electronics companies, as a very successful new product area because of the huge up-take of MEMS components in mobile devices during recent years. Third, key strategic issues in huge upcoming new consumer markets, such as wearables and IoT, are sensors and contextual awareness; areas which are uniquely solved by MEMS devices. And fourth, the sheer number of successful, high volume MEMS devices currently on the market, has created a huge pool of skilled MEMS developers and manufacturers which can be drawn upon for new devices and new start-up companies. All these factors dramatically influence how such companies get funding and how they operate. We will discuss all these issues as they relate specifically to new MEMS companies.

Niveditha Arumugam , Manager, Systems Design and Packaging
Engineering SiTime Corporation
Mobile applications require 32.768 kHz clock references with small form-factor, tight frequency stability, and ultra-low power at a competitive price. Legacy 32 kHz quartzbased technology has reached the limits of miniaturization, performance and cost.
SiTime’s MEMS technology has enabled a 32 kHz temperature compensated MEMS based oscillator (TCXO) in a chip-scale package (1.5mm x 0.8mm CSP) with ±5 ppm frequency stability over -40°C to 85°C, making it the world’s smallest and best-in-class 32 kHz TCXO. The SiTime solution enables increased functionality, smaller size and longer battery life in wearables, smartphones and other mobile devices.
This talk will provide an overview of the innovations that enabled this game-changing product for mobile applications. Topics will include innovations in MEMS/CMOS technology, chip scale packaging, and test and calibration techniques.
High-Speed Testing of Pressure Sensors
Gary Casey, President, Casey Engineering
This subject is perhaps unique in that there is no one answer that one can expect all experts to converge upon. In fact, small differences in sensor type, pressure range, and customer requirements may result in a considerably different answer to the question of how to test the sensor in production. As an example, a differential pressure sensor might be tested in essentially the same way as an absolute or gage sensor – but if there is a common mode requirement, the optimum method will likely be dramatically different.
There are essentially 4 aspects of testing, how to handle and transport the sensor, apply pressure, supply electrical power, and finally how to measure the result. Often the high-volume methodology grows from prototype and low-volume methodologies, usually leading to difficulties that could have been prevented. For example, the pressure application must be rapid, accurate and stable; and the traceability to NIST should be a short and robust path. Examples of solutions to these challenges will be discussed.
MEMS-based Autofocus in Cameras
Vijay Chandrasekharan, Ph.D., Invensas
Miniaturization of consumer electronics and inclusion of MEMS in these devices leads to a synergy of constant improvement and comes with its own challenges. This paper discusses the development and challenges of the only MEMS autofocus actuator in the world. The actuation range is a 100 um for the target focus range and can move a payload upto 4 mg to reach the desired focus range. The MEMS based design helps focus in at least half the time, with 1/100th the power with 1/5th the tilt of the current focus solution in the market that use voice coils. Large pay load with a 100 um of motion poses a significant design challenge for a MEMS device for both modeling and mechanical reliability. The non-hermetically sealed injection molded plastic package is one of the key components in the reliability of the MEMS device and is pushes the limits of the injection molding process. The device has a shock survivability of > 10,000g and over 12 drops from heights > 1.0m in a smartphone.
Passive Micro Sensors: When Power isn't an Option
Todd Christiansen, Chairman, CTO and Founder, HT Micro
Microsensors requiring no electrical power to provide their monitoring function along with the MEMS approaches enabling them are discussed. Several aspects are contributing to the high volume exploitation of these zero-power devices. This family of electromechanical sensors in effect operates as their own energy harvesters and extracts energy from their physical surroundings to monitor the measurand. Their output is provided through ultra-reliable switch contacts which in turn require specific feature sizes and materials that are unique relative to semiconductor devices. Long lifetime requires that the micro-electromechanical structures reside within integrated hermetic packages. By their nature these sensors also must be able to be easily positioned and integrated into strategic or remote positions within a system. Tremendous volume demand and growth is apparent for such devices in situations such as awareness and intermittent monitoring. Examples including inertial and magnetic switches are described.
Critical Success Factors for the Commercialization of MEMS:

Through Wafer Dicing without Saws or Lasers: High Productivity and Design Flexibility
David Lishan, Principal Scientist, Director-Technical Marketing, Plasma-Therm LLC
Wafer singulation technology is evolving. Although saws are widely accepted, the technology is running into performance boundaries regarding die strength (chipping), cutting speed for thin wafers, throughput for small die, large street widths, and are constrained to orthogonal streets. Laser dicing has been introduced to address some of these issues but limitations associated with induced damage and material incompatibilities have affected adoption.
This presentation will introduce a through wafer dicing using plasma etching that eliminates the constraints of saws and lasers, a new approach that utilizes standard dicing tapes and tape frames and enables non-orthogonal streets for layout flexibility, reduced street widths, chip/crack-free edges, and low stress corners. In addition, plasma etching dramatically increases singulation throughput as wafers become thinner to address the demands of smaller consumer form factors and volumes of smaller die (e.g. < 2mm2).
This new approach results in significantly higher yields, productivity increases, and encourages production of new die shapes. Examples highlighting this new technology will be presented along with various options for process flows.
Design of MEMS Piezoelectric Vibrational Energy Harvesters for Industrial and Commercial Applications
Kathleen M. Vaeth, Vice President of Engineering,
The increasing availability of small, lightweight, and affordable MEMS sensors and RF transmitters has opened up the possibilities of smart, integrated wireless sensor networks for monitoring and control of industrial equipment, building infrastructure, and transportation vehicles. Energy harvesting technology is key to enabling increased intelligence and proliferation of these networks, which are currently limited by available battery power. In this paper, we report the design, fabrication, modeling, and characterization of MEMS-based piezoelectric vibrational energy harvesters with power output suitable for supporting wireless sensors and sensor networks. Finite element modeling of the harvester resonant frequency and peak AC power output as a function of deflection shows good agreement with experimental data over a range of frequencies, and mechanical analysis of the harvester movement provides guidance in design for robustness. Demonstrations of harvesting vibrational energy to power real world objects will be presented, including a wireless sensor network for monitoring building temperature. The data obtained and lessons learned from the installation will be discussed.
