Abstract
Integrated circuits are supported by a semiconductor substrate wafer. Each integrated circuit includes an electrically active area. A thermally conductive protective structure is formed around the active areas of the various integrated circuits along scribe paths. The protective structure is located between the electrically active areas of the integrated circuits and a laser ablation area of the scribe paths. Separation of the integrated circuits is performed by scribing the semiconductor substrate wafer along the scribe paths. The process for scribing includes performing a laser ablation in the laser ablation area and then performing one of an etching or a physical scribing.
