Book Vacuum Packaging for Microelectromechanical Systems MEMS

Download or read book Vacuum Packaging for Microelectromechanical Systems MEMS written by and published by . This book was released on 2002 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Vacuum Packaging for MEMS Program focused on the development of an integrated set of packaging technologies which in totality provide a low cost, high volume product-neutral vacuum packaging capability which addresses all MEMS vacuum packaging requirements. The program balanced the need for near term component and wafer-level vacuum packaging with the development of advanced high density wafer-level packaging solutions. Three vacuum packaging approaches were pursued: large area component level; 4"/6" wafer-level; and wafer-level microshell encapsulation. The program focused on packaging for MEMS accelerometers and gyros; IR MEMS a-Si microbolometer and ferroelectric detectors; and RF MEMS resonators. Successful demonstrations were accomplished with IR MEMS microbolometers in sub 10 mTorr vacuum packages, inertial MEMS resonant accelerometers in sub 200 mTorr vacuum packages and an RF MEMS resonator demonstration. In addition to the successful demonstrations, numerous component and wafer-level vacuum packages passed extensive MIL standard environmental tests.

Book A Novel Vacuum Packaging Design Process for Microelectromechanical System Mems Quad Mass Gyroscopes

Download or read book A Novel Vacuum Packaging Design Process for Microelectromechanical System Mems Quad Mass Gyroscopes written by U. S. Army Research Laboratory and published by . This book was released on 2017-01-26 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been a growing need in society today for objects that humans use, both militarily and commercially, to be durable, faster, and efficient. From tanks and automobiles to unmanned aerial vehicles (UAVs) and robots, the need for improved performance is ubiquitous. Electronic sensors are no exception. In recent years, there has been a substantial amount of time and money invested in improving the performance and operability of position, navigation, and timing (PNT) systems. These systems need to be lighter, cheaper, and more power efficient to match the growing global dependence on them. In the defense sector, such devices should be able to match the various constraints and performance criteria of air and land robots, munitions, and constrained vehicle platforms. Currently, the standard navigation system that the US military uses is GPS. However, one of the drawbacks of GPS is its inherent weak signal and vulnerability to jamming by natural and unnatural means. This sole dependence on GPS technology may prove to be catastrophic if the signal is lost or broken. As such, development of microelectromechanical system(MEMS) inertial sensors that can provide navigation-grade performance can alleviate the military's reliance on a single PNT. This report focuses primarily on improving the performance of one PNT system, a resonant quadruple-mass gyroscope (QMG), which has been manufactured in-house by the US Army Research Laboratory (ARL) in Adelphi, Maryland.

Book Mems Packaging

Download or read book Mems Packaging written by Yung-cheng Lee and published by World Scientific. This book was released on 2018-01-03 with total page 363 pages. Available in PDF, EPUB and Kindle. 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 Massively Parallel Post Packaging for Microelectromechanical Systems MEMS

Download or read book Massively Parallel Post Packaging for Microelectromechanical Systems MEMS written by and published by . This book was released on 2003 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project has achieved many accomplishments toward "Massively Parallel Post-Packaging for MEMS." These achievements can be summarized as follows: (1) innovative bonding processes; (2) post-fabrication packaging demonstrations and characterizations on various MEMS devices; and (3) demonstrations and characterizations of post-fabrication device trimming. In summary, we were able to develop several new localized bonding processes, including eutectic bonding, fusion bonding, solder bonding, chemical vapor deposition (CVD) bonding, nano-second laser welding, inductive heating and bonding, ultrasonic bonding and rapid thermal processing (RTP) bonding. Every bonding process represents technology innovation and advancement. In addition, new material bonding systems were also investigated and established. These include aluminum-to-glass, aluminum-to-nitride, and aluminum-to-aluminum bonding systems. The new bonding processes and systems make possible the device encapsulation demonstrations, such as vacuum encapsulated micro resonators, by using localized aluminum-to-glass bonding, RTP bonding and localized CVD bonding. These vacuum bonded devices have gone through various types of characterization, including quality factor measurements, long-term stability monitoring and accelerated tests. In another device packaging area, selective trimming of micro resonators was successfully demonstrated by three different schemes, including active trimming by a localized heating and stressing effect, permanent trimming by localized CVD deposition and by pulsed laser deposition.

Download or read book Microelectromechanical Systems written by National Research Council and published by National Academies Press. This book was released on 1998-01-01 with total page 76 pages. Available in PDF, EPUB and Kindle. 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 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 rivalâ€"perhaps surpassâ€"the societal impact of integrated circuits.
