Silicon/Silica Substrates

 

We offer the ultra-flat silicon and silica wafers of the prime grade. These silicon and silica wafers are perfect for chemical deposition or cell growth while the 5mm x 5mm diced chips are ideal for direct AFM and SEM imaging. The silica substrates are silicon substrates uniformly coated with a 200 nm thermally grown SiO2 surface layer. Compared with the transitional chemical vapor deposition (CVD) method, the thermal oxidation provides a higher uniformity and a higher dielectric strength.
