Product Description
Product Overview
High-purity single crystal sapphire wafers with double-side polishing, available in diameters from 3" to 8". These semiconductor-grade substrates offer exceptional chemical, electrical, mechanical, optical, and thermal properties for demanding applications.
Material Properties
Synthetic sapphire is a single crystal form of corundum (Al2O3) with no porosity or grain boundaries, making it theoretically dense. This pure aluminum oxide material provides superior performance characteristics for high-reliability semiconductor systems.
