Patent ID: 7537952

Claim:
A method of manufacturing a micro electro-mechanical system (MEMS) device package, the method comprising: a) providing a device substrate having a MEMS active device and one or more lead lines electrically connected with the MEMS active device; b) forming, on a closure substrate, internal electrode pads and sealing pads positioned outside of the internal electrode pads to a predetermined height; c) bonding the device substrate and the closure substrate to each other through the sealing pads in such a way that the MEMS active device is positioned in the space provided by the internal electrode pads and the internal electrode pads come into contact with the lead lines; d) polishing the closure substrate to a predetermined thickness; e) forming via holes at the positions where the internal electrode pads are positioned on the closure substrate; and f) forming external electrode pads which are electrically connected with the internal electrode pads through the via holes, wherein the forming of internal electrode pads and sealing pads on a closure substrate comprises: b1) coating a seed layer on the entire surface of the closure substrate; b2) forming a plating frame for use in forming the internal electrode pads and the sealing pads on the seed layer through a photolithography process; b3) electrically plating a material, which is identical to the material forming the seed layer on the closure substrate, over the plating frame; and b4) removing the plating frame.
