This book was released on 2012-12-06 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: Micro Electro Mechanical Systems (MEMS) is already about a billion dollars a year industry and is growing rapidly. So far major emphasis has been placed on the fabrication processes for various devices. There are serious issues related to tribology, mechanics, surfacechemistry and materials science in the operationand manufacturingof many MEMS devices and these issues are preventing an even faster commercialization. Very little is understood about tribology and mechanical properties on micro- to nanoscales of the materials used in the construction of MEMS devices. The MEMS community needs to be exposed to the state-of-the-artoftribology and vice versa. Fundamental understanding of friction/stiction, wear and the role of surface contamination and environmental debris in micro devices is required. There are significantadhesion, friction and wear issues in manufacturing and actual use, facing the MEMS industry. Very little is understood about the tribology of bulk silicon and polysilicon films used in the construction ofthese microdevices. These issues are based on surface phenomenaand cannotbe scaled down linearly and these become increasingly important with the small size of the devices. Continuum theory breaks down in the analyses, e. g. in fluid flow of micro-scale devices. Mechanical properties ofpolysilicon and other films are not well characterized. Roughness optimization can help in tribological improvements. Monolayers of lubricants and other materials need to be developed for ultra-low friction and near zero wear. Hard coatings and ion implantation techniques hold promise.
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.
Download or read book Thin Film Encapsulation Methods for Large Area MEMS Packaging written by Armon Mahajerin and published by . This book was released on 2012 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past thirty years have seen rapid growth in products and technologies based on microelectromechanical systems (MEMS). However, one of the limiting factors in commercializing MEMS devices is packaging, which can be the most costly step in the manufacturing process. A MEMS package must protect the movable parts of the device while allowing it to interact with its surroundings. In addition, the miniaturization of sensors and actuators has made it possible to integrate MEMS fabrication with that of integrated circuit (IC) processing. Due to the varying requirements for different applications, a universal standard for packaging MEMS has been elusive. However, a growing trend has been the shift away from bonding a separate sealing substrate to the device substrate and toward thin film encapsulation. The latter method has the potential to reduce costs and materials usage while increasing device throughput and yield. Two thin film encapsulation methods for creating large area packaged cavities on top of silicon substrates have been developed based on porous membrane structures. The first approach uses thin polysilicon as a permeable membrane. The polysilicon is deposited on top of a doped oxide using low pressure chemical vapor deposition (LPCVD) to a thickness less than 300 nm. High temperature annealing drives the dopant atoms from the oxide into the polysilicon film, creating gaps within the film through which hydrofluoric acid (HF) vapor penetrates and etches the buried oxide. In addition, a process of rapidly depositing oxides greater than 10 um thick without cracking due to residual stress has also been demonstrated. This is accomplished by using plasma enhanced chemical vapor deposition (PECVD) steps of 2.5 um thickness with interceding rapid thermal annealing (RTA). The permeable polysilicon membrane technology provides the foundation for wafer-level encapsulation of MEMS devices inside the cavities by depositing a thick structural layer either under vacuum or at arbitrary pressure environments. The thin permeable polysilicon technique then evolves into a broader encapsulation method in which a semi-permeable film is constructed from carbon nanotubes (CNTs) and polysilicon. The dense forest of CNTs may be grown to a height from 10 um to hundreds of um as the structural foundation for the encapsulation layer. Conformally coating the CNTs with polysilicon by LPCVD generates natural pores within the thick membrane. HF vapor penetrates the semi-permeable film to selectively etch the bottom oxide layer, after which another polysilicon deposition seals the film, rendering it impermeable. The etching behavior has been characterized as a function of the CNT height and exposure time to HF vapor. The CNT/polysilicon thickness for a given vacuum-sealed cavity area has also been designed using finite element analysis (FEA). Furthermore, large sealing areas of more than 1x1 mm^2 have been successfully demonstrated. As such, this wafer-level encapsulation technology could find potential packaging applications of MEMS devices, including large area gyroscope structures.
