Alpha Nanotech Prime-Grade SSP 4'' Silicon Wafers (525 um, 1-30 ohm·cm, Qty: 1)
We offer the ultra-flat silicon and silica wafers of the prime grade in either 4'' wafer carriers or gel membrane boxes. The 4'' 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 vapour deposition (CVD) method, the thermal oxidation provides a higher uniformity and a higher dielectric strength.s.
