摘要:
The present disclosure includes micro-electro mechanical system (MEMS) structures and methods of forming the same. Substrates of the MEMS structures are bonded together by fusion bonding at high processing temperatures, which enables more complete removal of chemical species from the dielectric materials in the substrates prior to sealing cavities of the MEMS structures. Fusion bonding of MEMS structures reduces outgassing of chemical species and is compatible with the cavity formation process. The MEMS structures bonded by fusion bonding are mechanically stronger compared to eutectic bonding due to a higher bonding ratio. In addition, fusion bonding enables the formation of through substrate vias (TSVs) in the MEMS structures.
