Abstract:
The present invention provides a MEMS device such as a capacitive MEMS microphone that comprises a new design of air flow restrictor. An air channel includes a first internal wall and a second internal wall for air to flow between. A trench is recessed from the first internal wall, and an insert is extended from the second internal wall and inserted into the trench. The spatial relationship between the insert and the trench can vary or oscillate. Air resistance of the channel may be controlled by the trench depth. The air resistance is higher with a deeper trench. The invention has a significant effect on, for example, keeping the sound frequency response plot more flat on the low frequency part ranging from 20 Hz to 1000 Hz.

Claim (Index 7):
The MEMS device according to  claim 4 , further comprising a first electrical conductor,\n wherein the movable membrane constitutes at least a part of a second electrical conductor, or structurally connected to a second electrical conductor, wherein the first electrical conductor and the second electrical conductor are configured to have a second relative spatial relationship (SR 2 ) therebetween, wherein a second mutual capacitance (MC 2 ) exists between the first electrical conductor and the second electrical conductor; wherein said relative spatial relationship (SR 2 ) and said mutual capacitance (MC 2 ) can both be varied by an acoustic pressure impacting upon the first electrical conductor and/or the second electrical conductor along a range of impacting directions in 3D space; wherein said mutual capacitance (MC 2 ) is varied the most by an acoustic pressure impacting upon the first electrical conductor and/or the second electrical conductor along one direction among said range of impacting directions, said one direction being defined as the primary direction; wherein the first electrical conductor has a first projection along said primary direction on a conceptual plane that is perpendicular to said primary direction; wherein the second electrical conductor has a second projection along said primary direction on the conceptual plane; and wherein the first projection and the second projection have a shortest distance Dmin therebetween, and Dmin remains greater than zero regardless of that the first electrical conductor and/or the second electrical conductor is (are) impacted by an acoustic pressure along said primary direction or not.
