PSM (Plasma Surface Modification)
Semiconductor/DISPLAY chambers and internal structures made by Al and Ni, because it’s Good electrical conductivity and excellent corrosion resistance High quality characteristics according to device shrinkage Corrosion-resistant, plasma-resistant, chemical-resistant as required consequently Applied external coating such as anodizing, Y2O3, ALD with excellent properties.However, in processes above 200℃, problems such as cracks and arcing occur due
