Patent ID: 8921957

Claim:
A MEMS microphone, the MEMS microphone comprising: a back plate having a first side and a second side; a membrane coupled to the back plate, and having a first side and a second side; a support structure having a first side and a second side, the support structure including a support structure opening, wherein the first side of the support structure is coupled to the second side of the back plate; a substrate having a first side and a second side, the substrate including a substrate opening, wherein the first side of the substrate is coupled to the second side of the support structure; and an overtravel stop, wherein the overtravel stop limits a movement of the membrane away from back plate and including at least one of an overtravel stop structure coupled to the substrate, an overtravel stop structure formed as part of a carrier chip, and an overtravel stop structure formed as part of the support structure in the support structure opening, wherein the overtravel stop structure having a first side and a second side.
