Abstract: A method is provided for modifying a circuit containing a plurality of electrodes, within a substrate, comprising the steps of: (a) selecting at least two electrodes for making a connection; (b) removing materials covering the electrodes with a focused ion beam (FIB) or a laser to form contact holes for respectively exposing the electrodes; (c) depositing in the contact holes a conductive material for forming electrically conductive piers, by applying the focused ion beam (FIB) or laser, with gas molecules ejected from a nozzle; (d) disposing an electrically conductive viscid material over each of the electrically conductive piers; and (e) disposing an electrically conductive bridge floor to connect with the electrically conductive viscid material to form an electrically conductive bridge.

Abstract: The present invention relates to a method for modifying a circuit within a substrate, and the circuit includes a plurality of electrodes. The method includes: (a) selecting at least two from the plurality of electrodes for making connection; (b) removing materials covering said selected electrodes with a focused ion beam (FIB) or a laser 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) or a laser with gas molecules ejected from a nozzle; (d) disposing an electrically conductive viscid material over each of 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.

Abstract: The present invention relates to a method for retrieving a signal from a circuit within a substrate. The method comprising steps of: (a) selecting at least one from the plurality of electrodes for signal retrieving; (b) removing materials covering said selected electrode with a focused ion beam (FIB) or a laser to form contact hole for exposing said selected electrode; (c) depositing in said contact hole a conductive material for forming electrically conductive pier by applying said focused ion beam (FIB) or a laser over gas molecules; (d) disposing an electrically conductive viscid material over each electrically conductive pier; and (e) connecting the electrically conductive viscid material with a conductive wire. Thus, the signal could be retrieved from the electrically conductive wire.
