Patent ID: 8137995

Claim:
A method of manufacturing a semiconductor device having a first active device, comprising: providing a semiconductor wafer; forming a first active device on a first side of the semiconductor wafer; forming a first insulating layer over the first side of the semiconductor wafer; forming a first conductive layer over the first insulating layer; forming a first interconnect structure over the first insulating layer and first conductive layer, the first interconnect structure being electrically connected to the first active device through the first conductive layer; mounting a pre-fabricated temporary carrier to the first interconnect structure; after mounting the pre-fabricated temporary carrier, performing a chemical-mechanical polishing (CMP) process on a second side of the semiconductor wafer opposite the first side of the semiconductor wafer; forming a second active device on a second side of the semiconductor wafer; forming a second insulating layer over the second side of the semiconductor wafer; forming a second conductive layer over the second insulating layer; forming a second interconnect structure over the second insulating layer and second conductive layer, the second interconnect structure being electrically connected to the second active device through the second conductive layer; forming a third insulating layer over the second interconnect structure; and removing the pre-fabricated temporary carrier.
