Abstract
An integrated circuit chip and method of manufacturing the same which includes the use of a wafer cap having depressions therein for aligning with micro-electro-mechanical systems included in said integrated circuit when said cap is placed over a wafer containing numerous integrated circuits, the wafer is then cut, after the wafer cap is bound to the wafer. The wafer cap may also include a piezo-resistive element thereon for measuring pressure around the hermetically sealed MEMS.
