Research on Acid Etching Wafer With the High Glossiness
In order to improve the glossiness of acid etched wafer and achieve stable mass production, by optimizing process of producing silicon wafer, rotate and grind the wafer to be double-sided Insulated Bottle Holder grinding wafer, then acid etch the wafer.The glossiness of acid etched wafer reached more than 360 Gu (re fl ectivity greater than 98%) an
