1. A microelectromechanical (MEMS) device comprising:
- a microelectromechanical mechanism layer comprising;
a first part; and
a second part located on a first plane; and
at least one cover permanently attached to the mechanism layer for sealing at least a portion of the mechanism layer, the at least one cover comprising;
an inner surface;
an outer surface; and
a structure protruding from the inner surface of the at least one cover, the structure configured to permanently mechanically deflect the first part into a second planes,wherein the first part and the second part include a comb structure.

Abstract
A microelectromechanical system (MEMS) device with a mechanism layer having a first part and a second part, and at least one cover for sealing the mechanism layer. The inner surface of at least one of the covers is structured such that a protruding structure is present on the inner surface of the cover and wherein the protruding structure mechanically causes the first part to be deflected out of a plane associated with the second part.

6. A microelectromechanical (MEMS) device comprising:
-
a mechanism layer comprising; a first part; a second part; and a third part; and a top cover having a first surface; a bottom cover having a first surface; a first structure protruding from the first surface of the top cover, the first structure causes the first part to mechanically deflect out of a plane associated with the second part when the top cover is attached to the mechanism layer; and a second structure protruding from the first surface of the bottom cover, the second structure causes the third part to mechanically deflect out of the plane associated with the second part when the bottom cover is attached to the mechanism layer, wherein the top cover remains in fixed relation to the bottom cover after attachment to the mechanism layer. - View Dependent Claims (7, 8, 9, 10, 11, 12)
