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.
