Abstract:
A method of fabricating an integrated structure for MEMS device and semiconductor device comprises steps of: providing a substrate having a transistor thereon in a semiconductor device region and a first MEMS component thereon in a MEMS region; performing a interconnect process on the substrate in the semiconductor device region to form a plurality of first dielectric layers, at least a conductive plug and at least a conductive layer in the first dielectric layers; forming a plurality of second dielectric layers and an etch stopping device in the second dielectric layers on the substrate in a etch stopping device region; forming a plurality of third dielectric layers and at least a second MEMS component in the third dielectric layers on the substrate in the MEMS region; and performing an etching process to remove the third dielectric layers in the MEMS region.
Abstract:
A structure of micro-electro-mechanical systems (MEMS) electroacoustic transducer is disclosed. The MEMS electroacoustic transducer includes a substrate having a MEMS device region, a diaphragm having openings and disposed in the MEMS device region, a silicon material layer disposed on the diaphragm and sealing the diaphragm, and a conductive pattern disposed beneath the diaphragm in the MEMS device region. Preferably, a first cavity is also formed between the diaphragm and the substrate.
