The production of GaN epi on sapphire wafer manufacturing of semiconductors begins which are mainly prepared from silicon substrates. On the chemical purity and near-perfect crystalline properties of wafers the production of VLSI products and more specifically, processor chips depends. Therefore, with many complex phases like lapping and etching, silicon ingot growing, polishing, peripheral grinding, ingot slicing into wafers, raw material refining, wafer beveling, heat…
