Book excerpt: In Micro-Electro-Mechanical Systems packages, sealing pressure is one of the most important indicators of packaging quality. Traditional hermeticity testing methods are expensive and inconvenient. Solution for in-package pressure monitoring has long been appealing. Pirani sensor is a commonly used pressure sensor that can be integrated into Micro-Electro-Mechanical Systems packages. Our team is developing a hermetic packaging process for extremely sensitive and low noise accelerometers. A eutectic package sealing process is developed and evaluated. To verify the stability of environment inside the package, a lowcost, process flow compatible, space saving bondwire Pirani sensor has been explored. The sensing principle is based on resistance change of the filament is a function of pressure under constant electrical power. The feasibility of using the bondwire Pirani sensor has been thoroughly discussed. A novel four point measurement set up is implemented to achieve the accurate low resistance measurement. The bondwire Pirani sensor has a dynamic range from 0.1 Torr to about 50 Torr and is compatible with any micro-system such as resonators, gyroscopes, micro-mirrors, and micro-display systems among others. The sensor is applied to our own packaging process as pressure sensing element to detect pressure change. Long-term pressure stability for sealed packages is also measured by the bondwire Pirani sensor.

Book excerpt: MEMS sensors and actuators are enabling components for smartphones, AR/VR, and wearable electronics. MEMS packaging is recognized as one of the most critical activities to design and manufacture reliable MEMS. A unique challenge to MEMS packaging is how to protect moving MEMS devices during manufacturing and operation. With the introduction of wafer level capping and encapsulation processes, this barrier is removed successfully. In addition, MEMS devices should be integrated with their electronic chips with the smallest footprint possible. As a result, 3D packaging is applied to connect the devices vertically for the most effective integration. Such 3D packaging also paves the way for further heterogenous integration of MEMS devices, electronics, and other functional devices.This book consists of chapters written by leaders developing products in a MEMS industrial setting and faculty members conducting research in an academic setting. After an introduction chapter, the practical issues are covered: through-silicon vias (TSVs), vertical interconnects, wafer level packaging, motion sensor-to-CMOS bonding, and use of printed circuit board technology to fabricate MEMS. These chapters are written by leaders developing MEMS products. Then, fundamental issues are discussed, topics including encapsulation of MEMS, heterogenous integration, microfluidics, solder bonding, localized sealing, microsprings, and reliability.

Book excerpt: Microelectromenchanical systems (MEMS) is a revolutionary field that adapts for new uses a technology already optimized to accomplish a specific set of objectives. The silicon-based integrated circuits process is so highly refined it can produce millions of electrical elements on a single chip and define their critical dimensions to tolerances of 100-billionths of a meter. The MEMS revolution harnesses the integrated circuitry know-how to build working microsystems from micromechanical and microelectronic elements. MEMS is a multidisciplinary field involving challenges and opportunites for electrical, mechanical, chemical, and biomedical engineering as well as physics, biology, and chemistry. As MEMS begin to permeate more and more industrial procedures, society as a whole will be strongly affected because MEMS provide a new design technology that could rival--perhaps surpass--the societal impact of integrated circuits.

Available in PDF, EPUB and Kindle. Book excerpt: Seven years have passed since the publication of the previous edition of this book. During that time, sensor technologies have made a remarkable leap forward. The sensitivity of the sensors became higher, the dimensions became smaller, the sel- tivity became better, and the prices became lower. What have not changed are the fundamental principles of the sensor design. They are still governed by the laws of Nature. Arguably one of the greatest geniuses who ever lived, Leonardo Da Vinci, had his own peculiar way of praying. He was saying, “Oh Lord, thanks for Thou do not violate your own laws. ” It is comforting indeed that the laws of Nature do not change as time goes by; it is just our appreciation of them that is being re?ned. Thus, this new edition examines the same good old laws of Nature that are employed in the designs of various sensors. This has not changed much since the previous edition. Yet, the sections that describe the practical designs are revised substantially. Recent ideas and developments have been added, and less important and nonessential designs were dropped. Probably the most dramatic recent progress in the sensor technologies relates to wide use of MEMS and MEOMS (micro-electro-mechanical systems and micro-electro-opto-mechanical systems). These are examined in this new edition with greater detail. This book is about devices commonly called sensors. The invention of a - croprocessor has brought highly sophisticated instruments into our everyday lives.

Available in PDF, EPUB and Kindle. Book excerpt: Microsystems and MEMS technology is one of the biggest breakthroughs in the area of mechanical and electronic technology in recent years. This is the technology of extremely small and powerful devices, and systems built around them, which have mechanical and electrical components. MEMS technology is expanding rapidly, with major application areas being telecommunications, biomedical technology, manufacturing and robotic systems, transportation and aerospace. Academics are desperate for texts to familiarise future engineers with this broad-ranging technology. This text provides an engineering design approach to MEMS and microsystems which is appropriate for professionals and senior level students. This design approach is conveyed through good examples, cases and applied problems. The book is appropriate for mechanical and aerospace engineers, since it carefully explains the electrical/electronic aspects of the subject. Electrical engineering students will be given strong coverage of the mechanical side of MEMS, something they may not receive elsewhere.
