Abstract:
A lid for a micro-electro-mechanical device and a method for fabricating the same are provided. The lid includes a board with opposite first and second surfaces and a first conductor layer. The first surface has a first metal layer thereon. The first metal layer and the board have a recess formed therein. The recess has a bottom surface and a side surface adjacent thereto.
