Product Description

 

4H-N Silicon Carbide SiC Substrate 2inch 3inch 4inch 6inch 8inch Prime Grade Dummy Grade

Silicon carbide (SiC), commonly referred to as silicon carbide, is a compound formed by combining silicon and carbon. Silicon carbide seed crystal is an important form, which is widely used in semiconductor materials, ceramics, abrasives and other fields. Silicon carbide is second only to diamond in hardness, making it an excellent abrasive and cutting tool. Good thermal conductivity makes it suitable for high-temperature applications such as LEDs and power electronics. Good resistance to chemicals, especially acids and alkalis. Good resistance to chemicals, especially acids and alkalis. Good resistance to chemicals, especially acids and alkalis. Due to its superior properties, silicon carbide seed crystals have become an indispensable material in modern industry and technology.

The 4-inch 4H-N Silicon Carbide (SiC) wafer is a semiconductor material with a 4H polytype crystal structure.

It  is typically oriented as (0001) Si-face or (000-1) C-face.

These wafers are N-type, doped with nitrogen, and have a thickness of about 350 µm.

The resistivity of these wafers generally falls between 0.015 to 0.025 ohm·cm, and they often feature a polished surface on one or both sides.
