Claim Text:
1. A method of making a semiconductor device, comprising: providing a substrate including a base and a plurality of conductive posts extending from the base; forming a contact pad over a surface of a first conductive post of the plurality of conductive posts; providing a semiconductor die including a sensor area; disposing the semiconductor die over the base between the conductive posts with a back surface of the semiconductor die opposite an active surface of the semiconductor die disposed below the contact pad; forming an interconnect structure between the semiconductor die and the first conductive post; disposing a penetrable adhesive layer over the semiconductor die and sensor area with a portion of the interconnect structure embedded within the penetrable adhesive layer; disposing a sacrificial layer over the penetrable adhesive layer; depositing an encapsulant around the semiconductor die and conductive posts with a surface of the encapsulant coplanar with a surface of the sacrificial layer; and removing the sacrificial layer while leaving the penetrable adhesive layer over the semiconductor die and sensor area.
