What is a sic wafer

A SiC wafer is a semiconductor material that has excellent electrical and thermal properties. It is a high-performance semiconductor that is ideal for a wide variety of applications. In addition to its high thermal resistance, it also features a very high level of hardness.

 

Classification

  Silicon carbide SiC substrates can be divided into two categories: semi-insulated (High Purity un-dopend and V-doped 4H-SEMI) silicon carbide substrates with high resistivity (resistorivity ≥107Ω·cm), and conductive silicon carbide substrates with low resistivity (the resistivity range is 15-30mΩ·cm).

Industrial chain

The silicon carbide SiC industrial chain is divided into substrate material preparation, epitaxial layer growth, device manufacturing and downstream applications. Silicon carbide monocrystals are usually prepared by physical vapor transmission (PVT method), and then epitaxial sheets are generated by chemical vapor deposition (CVD method) on the substrate, and the relevant devices are finally made. In the industrial chain of SiC devices, due to the difficulty of substrate manufacturing technology, the value of the industrial chain is mainly concentrated in the upstream substrate link.
