Patent ID: 8653661

Claim:
A package having a Micro-Electro-Mechanical System (MEMS) element, comprising: a protection layer having opposite first and second surfaces and a plurality of openings in communication with the first and second surfaces; a plurality of conductors formed in the openings of the protection layer, respectively, wherein each of the conductors has opposite third and fourth surfaces, and the fourth surface of each of the conductors is flush with the second surface of the protection layer; a plurality of conductive pads formed on the first surface of the protection layer and the third surface of each of the conductors, for electrically connecting with the conductors, wherein the conductive pads are free from being formed on the fourth surface of each of the conductors; a plurality of conductive bumps disposed on the conductive pads and electrically connected to the conductive pads; a MEMS chip disposed on the conductive bumps and electrically connected to the conductive pads by the conductive bumps; and an encapsulant formed on the protection layer for encapsulating the MEMS chip, wherein the fourth surface of each of the conductors is exposed from the second surface of the protection layer and the encapsulant.
