Patent ID: 8742557

Claim:
A device comprising: a microelectromechanical systems (MEMS) device; a die configured to support the MEMS device, the die having a first side and a first coefficient of thermal expansion; a cover plate attached to the die, the cover plate having a first side and a second coefficient of thermal expansion; a package attached to the cover plate, the package having a third coefficient of thermal expansion, wherein the third coefficient of thermal expansion is higher than the second coefficient of thermal expansion; at least one first electrically conductive attachment device configured to attach the first side of the die to the first side of the cover plate; and at least one second electrically conductive attachment device configured to attach the first side of the cover plate to the package, wherein the at least one second electrically conductive attachment device is electrically coupled to the at least one first electrically conductive attachment device by a conductive trace disposed on the first side of the cover plate.
