    • 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 having a first dimension and the openings having a second dimension are arranged alternately, and the first dimension is not equal to the second dimension. 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.
    • 提供了微机电系统(MEMS)隔膜。 MEMS隔膜包括第一导电层,第二导电层和第一介电层。 第一导电层设置在基板上并且具有多个开口。 具有第一尺寸的开口和具有第二尺寸的开口交替布置,并且第一尺寸不等于第二尺寸。 第二导电层设置在第一导电层和衬底之间。 第一介电层部分地设置在第一导电层和第二导电层之间,使得第一导电层的一部分被悬挂。
