  • Patent number: 9783412
    Abstract: A MEMS device for use in some embodiments in a microphone or pressure sensor and method of making the same wherein a portion of the package surrounding the acoustic port is deformed either away from, towards, or both away from and towards the interior of the package. By providing this raised area proximate the acoustic port, external debris is less likely to enter the acoustic port and damage the fragile MEMS die. Further, internal attachment material holding the MEMS die to the inside of the package is prevented by flowing into and obscuring the acoustic port. The advantages of this design include longer operation lifetimes for the MEMS device, greater design freedom, and increases in production yield.
