Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: providing a workpiece, the workpiece including an insulating layer disposed thereon and a first conductive line disposed within the insulating layer, the first conductive line having a first top surface, the insulating layer having a second top surface, wherein the second top surface of the first insulating layer is substantially coplanar with the first top surface of the first conductive line; depositing an encapsulating protective material over the first top surface of the first conductive line and over the second top surface of the insulating layer; depositing at least one material layer over the encapsulating protective material; patterning the at least one material layer to form a patterned structure over the first conductive line; depositing a masking material over the patterned structure and the encapsulating protective material; patterning the masking material; and patterning the encapsulating protective material using the masking material as a mask, wherein the encapsulating protective material protects the first conductive line during the patterning of the at least one material layer, and wherein the encapsulating protective material comprises a conductive material that is electrically coupled to the first conductive line.
