SiC dummy wafer "Achieving ultra-high purity, high heat resistance, and high wear resistance"

It is made of unique CVD-SiC and possesses characteristics of ultra-high purity, high corrosion resistance, high oxidation resistance, high heat resistance, and high wear resistance.

The SiC dummy wafer, which boasts ultra-high purity and excellent corrosion and heat resistance, can be used for long-term recycling and is suitable for LP-CVD, high-temperature diffusion, and CMP processes. ◆ Contributes to cost reduction  ・Long-term recycling is possible  ・Ultra-high purity with excellent corrosion and heat resistance  ・Long-term use leads to savings on silicon wafers and reduces management labor for replacing and cleaning dummy wafers 【Features】  ・High purity (purity at the ppm level)  ・High oxidation resistance (can be used in oxidizing atmospheres for extended periods)  ・High corrosion resistance (can remove deposited films and surface contamination with wet cleaning only)  ・Low diffusion coefficient (internal diffusion of surface contamination into SiC is difficult)  ・Deposited films are less likely to peel off, contributing to reduced particles *For more details, please contact us.
