Interconnect routing over semiconductor for editing through the back side of an integrated circuit

摘要

Circuit edits may be performed through the back side of an 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. An insulating layer is not deposited over the first and second circuit edit connection targets and the exposed semiconductor substrate. Next, a conductor is deposited over the circuit edit connection targets from the back side of the integrated circuit to couple together the circuit edit connection targets.
