Patent ID: 7772026

Claim:
A method of manufacturing a micro electro-mechanical system (MEMS) device package, the method comprising: a) forming several via holes having a predetermined depth on a closure substrate; b) forming a seed layer on the entire surface of the closure substrate formed with the via holes, the seed layer being formed in a predetermined thickness on inner walls of the via holes without completely filling in the via holes; c) forming internal electrode pads and sealing pads on the seed layer; d) bonding the closure substrate, which is formed with the internal electrode pads and the sealing pads, and a device substrate, which is formed with a MEMS active device on the center of the top surface thereof, to each other through the internal electrode pads and the sealing pads; e) polishing the closure substrate to a predetermined thickness, so that the via holes and the seed layer parts formed in the predetermined thickness in the via holes are exposed; and f) forming, on the closure substrate, external electrode pads which are electrically connected with the seed layer parts formed in the via holes, wherein the bonding the closure substrate and the device substrate to each other through the internal electrode pads and the sealing pads comprises direct bonding using a bonding layer formed on the device substrate, and wherein the bonding layer openings formed to correspond to clearances of the inner electrode pads formed corresponding to the via holes, so that an upper surface of the device substrate corresponding to the openings is exposed to an exterior.
