DOWNLOAD EBOOKThis 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 EBOOKMEMS 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 EBOOKPackaging of microelectronics has been developing since the invention of the transistor in 1947. With the increasing complexity and decreasing size of the die, packaging requirements have continued to change. A step change in package requirements came with the introduction of the Micro-Electro-Mechanical System (MEMS) whereby interactions with the external environment are, in some cases, required. This resource is a rapid, definitive reference on hermetic packaging for the MEMS and microelectronics industry, giving practical guidance on traditional and newly developed test methods. This book includes up-to-date and applicable test methods for today’s package types. The authors cover the history and development of packaging, along with a view to understanding initial hermeticity testing requirements and the subsequent limitations of these methods when applied to new package types.

DOWNLOAD EBOOKThe 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.
