47.5 mm ± 1.5 mm SiC Epitaxial Wafer 150.0 mm +0mm/-0.2mm Parallel to<11-20>±1°
JDCD03-001-003
Overview
Currently, there are two main types of SiC wafers. The first type is the polished wafer, which is a single silicon carbide disc. It is made of high-purity SiC crystals, and can be 100mm or 150mm in diameter. It is used in high-power electronics. The second type is the epitaxial crystalline silicon carbide wafer. This type of wafer is created by adding layers of single silicon carbide crystals to a surface. This method requires precise control of the thickness of the material, and is referred to as n-type epitaxy.
