Introduction 4H-SiC's superior material properties enable thinner, more heavily doped drift layers that can withstand high breakdown voltages, resulting in lower specific on-resistance (Ron,sp) and making unipolar devices more viable compared to silicon-based counterparts.
The key benefit of this additional JFET and channel region is the large increase in channel density.

As key components during the process of gas being gathered via casing, gas tight premium connection’s thread and sealing surface processing have higher requirements, which need to adopt numerical control lathe processing.
In addition, the influence caused by material, quantity and the quality requirement, etc, all need to be thought comprehensively to determine machining process.
