Recently, hyperpure silicon wafers  manufacturer Siltronic AG has signed an agreement with the Belgian nano-electronics research institute imec on the development of silicon wafers with a gallium nitride layer as partner of imec’s GaN-on-Si industrial affiliation program (IIAP). According to the agreement, the two companies target to enable production of solid-state lighting such as LEDs and power semiconductors of the next generation on 200 mm silicon wafers. Siltronic can draw on decades of experience in epitaxial deposition of materials on silicon substra...
