Abstract
According to the present invention, a micro-electro-mechanical system (MEMS) device comprises: a thin film structure including at least a metal layer and a protection layer deposited in any order; and a protrusion connected under the thin film structure. A preferred thin film structure includes at least a lower protection layer, a metal layer and an upper protection layer. The MEMS device for example is a capacitive MEMS acoustical sensor.
