Patent ID: 8183130

Claim:
A method of making a semiconductor device, comprising: providing a semiconductor wafer having a substrate; forming a first insulating layer over an active surface of the semiconductor wafer; forming an integrated passive device (IPD) structure over the first insulating layer, the IPD structure including, (a) forming a first conductive layer over the first insulating layer, (b) forming a second insulating layer over the first conductive layer, (c) forming a second conductive layer over the second insulating layer, (d) forming a third insulating layer over the second conductive layer and second insulating layer, (e) forming a third conductive layer over the second conductive layer, (f) forming a fourth insulating layer over the third conductive layer and third insulating layer, and (g) forming a fourth conductive layer between portions of the third conductive layer; forming a first via through the fourth conductive layer and third insulating layer and partially through the substrate; filling the first via with conductive material to form a conductive via; forming a second via through a back surface of the semiconductor wafer opposite the active surface to the conductive via; forming a shielding layer over the back surface of the semiconductor wafer and extending into the second via to the conductive via; and singulating the semiconductor wafer through the conductive via.
