Abstract:
Various embodiments of the present disclosure are directed towards a microelectromechanical system (MEMS) device. The MEMS device includes a dielectric structure disposed over a first semiconductor substrate, where the dielectric structure at least partially defines a cavity. A second semiconductor substrate is disposed over the dielectric structure. The second semiconductor substrate includes a movable mass, where opposite sidewalls of the movable mass are disposed between opposite sidewall of the cavity. An anti-stiction structure is disposed between the movable mass and the dielectric structure, where the anti-stiction structure is a first silicon-based semiconductor.
