Abstract:
A method for making a pressure sensor die package comprising:providing a pressure sensor die, said pressure sensor die comprising a pressure sensor die first surface and a pressure sensor die second surface, opposite said pressure sensor die first surface; providing a substrate, said substrate comprising a substrate first surface and a substrate second surface, opposite said substrate first surface, said substrate first surface comprising a die attach region; attaching said pressure sensor die second surface to said substrate first surface in said die attach region; and applying encapsulant to said substrate first surface and said pressure sensor die, said encapsulant comprising an outer surface, said encapsulant being applied such that said encapsulant forms a cavity over a first region of said pressure sensor die first surface, said cavity comprising side surfaces and a bottom surface wherein; said first region of said pressure sensor die first surface is said bottom surface of said cavity and said first region of said pressure sensor die first surface is not covered by said encapsulant.
