Patent ID: 7422970

Claim:
A method for modifying a circuit within a substrate, the circuit including a plurality of electrodes, the method comprising steps of: (a) selecting at least two from the plurality of electrodes for making an electrical connection between the at least two electrodes; (b) removing materials covering said selected electrodes with a focused ion beam (FIB) to form contact holes for respectively exposing said selected electrodes; (c) depositing in said contact holes a conductive material for forming electrically conductive piers by applying said focused ion beam (FIB) and gas molecules ejected from a nozzle; (d) disposing an electrically conductive viscid material selectively over each of said electrically conductive piers, thereby forming discrete electrical connections between only said electrically conductive piers; and (e) disposing an electrically conductive bridge floor to connect with each of the electrically conductive viscid material to form an electrically conductive bridge.
