Mitsui's SiC wafer, excellent in ultra
high-purity, high corrosion resistance, and heat resistance, can be used as
a recyclable wafer.
It is especially usefull as “dummy wafer and film thickness monitor wafer”
for LP-CVD and as “dummy wafer” for high temperature diffusion processes.
Features
|
|
Ultra high-purity, non-porous SiC
wafer produced by CVD method with impurities of ppb level.
|
|
|
No concern of process contamination
because of a markedly low diffusion coefficient of alkaline metal and
heavy metal in high temperature.
|
|
|
High corrosion resistance to harsh
chemicals such as HF +HNO3, allows for only
deposited films to be removed easily and selectively by wet etching. So
repeated usage is possible and economically advantageous.
|
|
|
Deposited films do not tend to peel
off due to the similar thermal expansion coefficients of SiC, SiN,
Poly-Si, etc. This results in a minimum of particles in the processes.
|
|
|
There is very little thermal
deformation at high temperature process.
