Abstract

A process of manufacturing selectively restructurable conductive links between circuit elements and corresponding spare elements on a semiconductor. A continuous green light laser directed at a non-conductive amorphous region in the links causes the region to recrystallize. This makes the link electrically conductive thereby joining the circuit elements to a corresponding spare element on the semiconductor. The method permits for high density packing of circuit elements and creates a link without producing bulk material movement.
