The windows protect the active elements of the microdevice from contaminants, while allowing light to pass into and out of the hermetically sealed microdevice package. Windows may be batch produced, reducing the cost of production, by fusing multiple metal frames to a single sheet of glass. In order to allow windows to be welded atop packages, disclosed embodiments keep a lip of metal without any glass after the metal frames are fused to the sheet of glass. Several techniques may accomplish this goal, including grinding grooves in the glass to provide a gap that prevents fusion of the glass to the metal frames along the outside edges in order to form a lip.

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.
