摘要:
A MEMS microphone including a carrier board and a MEMS chip mounted thereon over a sound opening. A filter chip includes a bulk material with an aperture covered and closed by a mesh. The mesh includes a layer of the filter chip with parallel through-going first holes structured in the layer. The filter chip is arranged in or on the carrier board such that the mesh covers the sound opening.
