Abstract:
A circuit board structure and a fabrication method thereof are disclosed. The circuit board structure includes a carrying board having a first and an opposite second surface and having at least one through cavity formed therein; a semiconductor chip disposed in the through cavity of the carrying board; an adhesive material filling the gap between the through cavity of the carrying board and the semiconductor chip to fix the semiconductor chip in the through cavity; and a reinforcing layer disposed on the second surface of the carrying board and the inactive surface of the semiconductor chip, thereby increasing the strength of the carrying board as well as the reliability of the circuit board.

Abstract:
A lid for a MEMS device and the relative manufacturing method. The lid includes: a first board with opposite first and second surfaces having first and second metal layers disposed thereon, respectively, wherein a through cavity extends through the first board and the first and second metal layers; a second board with opposite third and fourth surfaces; an adhesive layer sandwiched between the second surface of the first board and the third surface of the second board to couple the first and second boards together such that the through cavity is closed by the second board, thereby forming a recess; and a first conductor layer coating the bottom and the side surfaces of the recess.
