Abstract:
A method for performing a circuit edit in an integrated circuit die, the method comprising:exposing from a backside of the integrated circuit die first and second circuit edit connection targets through a semiconductor substrate of the integrated circuit die by removing a backside portion of the semiconductor substrate above each of the first and second circuit edit connection targets;vapor depositing a polyimide layer globally over the backside of the semiconductor substrate of the integrated circuit die using a vapor deposition polymerization process;re-exposing the first and second circuit edit connection targets through the polyimide layer;depositing a conductor over the polyimide layer between the first and second circuit edit connection targets to couple together the first and second circuit edit connection targets, wherein depositing the conductor is performed using a laser metal chemical vapor deposition system; andcuring only a portion of the polyimide layer under the conductor simultaneously with depositing of the conductor.
