Abstract:
1. A method of assembling a semiconductor sensor device, the method comprising: mounting a pressure sensing die and at least one other die on a substrate; electrically interconnecting the pressure sensing die and the at least one other die; covering an active region of the pressure sensing die with pressure sensitive gel material; mounting a cap having a cavity formed therein over the pressure sensing die, wherein: encapsulating the at least one other die and at least a portion of the cap with a molding compound on an upper surface of the substrate; and singulating through the substrate and the molding compound such that at least a portion of the side vent stack is severed from the cap, thereby forming a vent opening in the cap that exposes the gel-covered active region of the pressure sensing die to ambient atmospheric pressure outside the sensor device.
