Abstract
A sensing membrane applied to a micro-electro-mechanical system (MEMS) device includes a body, a stress releasing structure and a connecting portion. The stress releasing structure for releasing a membrane residual stress surrounds the body. The stress releasing structure has several first perforations and several second perforations. The first perforations are located between the body and the second perforations. The connecting portion connects the stress releasing structure and a substrate of the MEMS device.
