Abstract

Directed energy conversion of semiconductors by the directed energy fusion of a selective region of a semiconductor layer to provide a conductive path through the layer. A conductive path is formed through a semiconductive layer through opposed electrodes by conversion of the semiconductive region, for example, by laser energy applied to change the structure in the region extending between the electrodes. The change in conductivity of the path is monitored and used to control the formation of the conductive path by controlling the directed energy source.
