Abstract
The present disclosure provides one embodiment of an integrated microphone structure. The integrated microphone structure includes a first silicon substrate patterned as a first plate. A silicon oxide layer formed on one side of the first silicon substrate. A second silicon substrate bonded to the first substrate through the silicon oxide layer such that the silicon oxide layer is sandwiched between the first and second silicon substrates. A diaphragm secured on the silicon oxide layer and disposed between the first and second silicon substrates such that the first plate and the diaphragm are configured to form a capacitive microphone.
