Abstract:
1. A Micro-Electro Mechanical System (MEMS) device package comprising: a device substrate having a surface on which a MEMS active device is formed; multiple sealing pads arranged around the MEMS active device; a cap substrate bonded to the device substrate through the multiple sealing pads, the cap substrate comprising a trench, within which the MEMS active device is positioned, and via holes; and one or more outer electrode pads formed on a surface of the cap substrate to be electrically connected with the multiple sealing pads through the via holes, wherein the sealing pads seal the MEMS active device from an outside of the trench, provide one or more electric paths for the MEMS active device, wherein each of the sealing pads encloses the MEMS active device in a form of a continuously connected closed curve, and wherein the sealing pads are disposed on and below an undersurface of the cap substrate, and between the trench and the via holes.
