Abstract:
1. A method of forming a semiconductor device, the method comprising: providing a substrate, the substrate having a first side and a second side opposite the first side; forming an opening extending from the first side of the substrate into the substrate; forming a first liner along sidewalls of the opening; forming a conductive material over the first liner in the opening; thinning the second side of the substrate, thereby exposing at least a portion of the first liner; removing at least a portion of the first liner interposed between the conductive material and the substrate and removing at least a portion of the first liner extending over a dielectric layer on the first side of the substrate; and forming, after the removing, a second liner interposed between the conductive material and the substrate and extending over at least a portion of the dielectric layer formed on the first side of the substrate.
