Abstract:
1. A method for modifying the impedance of a semiconductor component, said semiconductor component comprising a first conductive region defining a laid down base conductive path, said first conductive region comprising a first link member and a second link member, said first region being a doped region having a heat modifiable dopant profile and a second region contiguous with the first region, said second region being a doped region having a dopant profile rendering said second region non-conductive relative to said first region, said first and second link members being disposed in juxtaposition such that said first and second link members are separated by a gap region defined by said second region, said second region having a heat modifiable dopant profile, at least with respect to said gap region, said method comprising applying a bridging cycle to one or more preselected bridging areas, each said bridging area comprising a gap region component comprising at least a portion of the gap region, a first link component comprising at least a portion of said first link member, and a second link component comprising at least a portion of said second link member, so as to form a discrete conductive bridge across said gap region connecting said first link member and said second link member, said bridging cycle comprising applying one or more heating/cooling treatments to one or more preselected target areas of bridging area, each heating/cooling treatment comprising directing a focused heating source to melt a preselected target area of a bridging area so as to thereby alter the dopant profile of the melted preselected target area and allowing said melted preselected target area to solidify with an altered dopant profile.
