    Abstract: The present invention relates to a silicon based MEMS microphone, comprising a silicon substrate and an acoustic sensing part supported on the silicon substrate, wherein a mesh-structured back hole is formed in the substrate and aligned with the acoustic sensing part, the mesh-structured back hole includes a plurality of mesh beams which are interconnected with each other and supported on the side wall of the mesh-structure back hole, the plurality of mesh beams and the side wall define a plurality of mesh holes which all have a tapered profile and merge into one hole in the vicinity of the acoustic sensing part at the top side of the silicon substrate. The mesh-structured back hole can help to streamline the air pressure pulse caused, for example, in a drop test and thus reduce the impact on the acoustic sensing part of the microphone, and also serve as a protection filter to prevent alien substances such as particles entering the microphone.
