    摘要: The present disclosure provides a micro-electro-mechanical systems (MEMS) device and a method for fabricating such a device. In an embodiment, a MEMS device includes a substrate, a dielectric layer above the substrate, an etch stop layer above the dielectric layer, and two anchor plugs above the dielectric layer, the two anchor plugs each contacting the etch stop layer or a top metal layer disposed above the dielectric layer. The device further comprises a MEMS structure layer disposed above a cavity formed between the two anchor plugs and above the etch stop layer from release of a sacrificial layer.

    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.
