Patent ID: 8466059

Claim:
A method of forming a semiconductor device, the method comprising: providing a first substrate, the first substrate having a through-substrate via extending from a first side into the first substrate; exposing the through-substrate via on a second side of the first substrate, the through-substrate via extending beyond a surface on the second side of the first substrate by a first distance; forming a first isolation film having a thickness less than the first distance, the first isolation film formed along the second side of the first substrate such that the through-substrate via is exposed; forming a first conductive element on the through-substrate via, the first conductive element extending over an upper surface of the first isolation film; forming a second isolation film on the first isolation film and the first conductive element; and forming a second conductive element electrically coupled to the first conductive element, the second conductive element extending over the upper surface of the second isolation film.
