Abstract:
Structures and formation methods of a semiconductor device structure are provided. A semiconductor device structure includes a first dielectric layer and a second dielectric layer over a semiconductor substrate. A cavity penetrates through the first dielectric layer and the second dielectric layer. The semiconductor device structure also includes a first movable membrane between the first dielectric layer and the second dielectric layer. The first movable membrane is partially exposed through the cavity. The first movable membrane includes first corrugated portions arranged along an edge of the cavity.

Claim (Index 15):
A method for forming a semiconductor device structure, comprising:\n forming a first dielectric layer over a semiconductor substrate; partially removing the first dielectric layer to form first recesses; forming a first membrane over the first dielectric layer, wherein the first membrane fills the first recesses so that the first membrane comprises first corrugated portions; forming a second dielectric layer over the first dielectric layer to cover the first corrugated portions; and partially removing the semiconductor substrate, the first dielectric layer and the second dielectric layer to form a cavity exposing the first corrugated portions.
