Ürün Açıklaması
Product Overview The 12-inch (300mm) sapphire wafer is a high-end large-format specification in the sapphire substrate sector. It is fabricated from 4N5 to 5N grade high-purity synthetic single-crystal alumina (α-Al₂O₃), with single-crystal ingots grown via advanced processes such as the Kyropoulos method, followed by semiconductor-grade procedures including multi-wire slicing, precision lapping and chemical mechanical polishing (CMP). As a large-size foundational substrate
