JDCD08-001-005 4inch R-Plane Sapphire Substrate Wafer
Sapphire's high purity and strength is an excellent and industry-accepted material for Semiconductor manufacturing. Its durability and scratch resistance make Sapphire ideal for vacuum environments and high plasma resistance to withstand etching.
In practical production, the sapphire wafer is made by cutting the crystal bar and then grinding and polishing. Generally, the semiconductor wafer is cut into a wafer by wire cutting or multi-wire cutting machine.
