4H-N Silicon Carbide SiC Substrate 2inch 3inch 4inch 6inch 8inch 12inch Prime Grade Dummy Grade
Product Description
4H-N Silicon Carbide SiC Substrate 2inch 3inch 4inch 6inch 8inch 12inch 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.
Silicon carbide wafers are renowned for their excellent thermal conductivity.
And also for a wide bandgap of 3.23 eV, high breakdown electric field, and significant electron mobility.
They exhibit high hardness, making them resistant to wear and thermal shock, and have exceptional chemical and thermal stability.
These properties make SiC wafers suitable for applications in harsh environments, including high-power, high-temperature, and high-frequency electronic devices.
