MEMS DIAPHRAGM
First Claim
1. A MEMS diaphragm, comprising:
- a first conductive layer, disposed on a substrate and having a plurality of openings, wherein the openings have the same dimension, and a distance between the adjacent openings is gradually increased toward an edge of the first conductive layer;
a second conductive layer, disposed between the first conductive layer and the substrate; and
a first dielectric layer, partially disposed between the first conductive layer and the second conductive layer, so that a portion of the first conductive layer is suspended.

Abstract
A microelectromechanical system (MEMS) diaphragm is provided. The MEMS diaphragm includes a first conductive layer, a second conductive layer and a first dielectric layer. The first conductive layer is disposed on a substrate and having a plurality of openings. The openings have the same dimension, and the distance between the adjacent openings is gradually increased toward the edge of the first conductive layer. The second conductive layer is disposed between the first conductive layer and the substrate. The first dielectric layer is partially disposed between the first conductive layer and the second conductive layer, so that a portion of the first conductive layer is suspended.
