Abstract
A method and an apparatus for performing circuit edits through the back side of a flip-chip packaged integrated circuit die. In one embodiment, a circuit edit is achieved by exposing first and second circuit edit connection targets through a semiconductor substrate of the integrated circuit die from the back side. Next, an insulating layer is deposited over the first and second circuit edit connection targets and the exposed semiconductor substrate. Next, the circuit edit connection targets are re-exposed through the insulating layer and a conductor is deposited over the re-exposed circuit edit connection targets and the deposited insulating layer from the back side of the integrated circuit to couple together the circuit edit connection targets.
