Patent ID: 8409970

Claim:
A method of making a semiconductor device, comprising: providing a silicon semiconductor substrate; forming passive circuit elements including a capacitor and inductor over the silicon semiconductor substrate by, (a) forming a first insulating layer over the silicon semiconductor substrate, (b) forming a first conductive layer over the first insulating layer, (c) forming a second insulating layer over the first conductive layer, (d) forming a second conductive layer over the second insulating layer, (e) forming a third conductive layer over the first insulating layer and disposed apart from the first conductive layer, (f) forming a first passivation layer over the first, second, and third conductive layers, (g) forming a fourth conductive layer over the first passivation layer, the fourth conductive layer including individual portions in electrical contact with the second and third conductive layers to form multiple passive circuit elements, (h) forming a second passivation layer over the fourth conductive layer and first passivation layer, and (i) removing a portion of the second passivation layer to expose the fourth conductive layer; attaching a carrier to the second passivation layer opposite the silicon semiconductor substrate; removing the silicon semiconductor substrate with back grinding, silicon wet etching, plasma etching, or chemical mechanical polishing (CMP) to expose the first insulating layer; disposing a non-silicon substrate over the first insulating layer opposite the second passivation layer; removing the carrier; forming an electrical interconnect over the second passivation layer; and singulating the non-silicon substrate.
