Patent ID: 8368187

Claim:
A method of making a semiconductor device, comprising: providing a temporary substrate; forming a first insulating layer over the temporary substrate; forming a first conductive layer in the first insulating layer; providing a first semiconductor die including a stress sensitive region; disposing the first semiconductor die over the first insulating layer and electrically connected to the first conductive layer with dam material between the first semiconductor die and first insulating layer adjacent to the stress sensitive region; depositing an encapsulant over the first semiconductor die while the dam material blocks the encapsulant leaving a gap between the stress sensitive region and first insulating layer; removing the temporary substrate; and forming a first build-up interconnect structure over the first insulating layer by, (a) forming a second insulating layer over the first insulating layer, and (b) forming a second conductive layer within the second insulating layer with the gap isolating the stress sensitive region from the first build-up interconnect structure.
