Patent ID: 7560857

Claim:
A package structure of a micro-electromechanical system (MEMS) type microphone, comprising: a substrate, having a connection pad; a MEMS microphone module, electrically coupled to the connection pad of the substrate, comprising an acoustic wave sensing portion; an acoustic wave cover, fixed on the MEMS microphone module to be in physical contact with the MEMS microphone module, for covering without contacting the acoustic wave sensing portion to define an acoustic wave cavity space, wherein the acoustic wave cover comprises an opening for the acoustic wave to enter or exit out of the acoustic wave cavity space; and an encapsulant, encapsulating the substrate, the MEMS microphone module and the acoustic wave cover to be in physical contact with the MEMS microphone module, wherein a surface of the acoustic wave cover is exposed, and wherein the exposed surface of the acoustic wave cover is along a same plane as a surface of the encapsulant.
