Alpha Nanotech Prime-Grade 4'' Silicon Wafers (P-Type, 1000 um) (Qty: 10)

Ultra-Flat Silicon Wafers Prime/CZ Virgin Grade; Orientation: <100>; Resistivity: 1-30 Ω; Type: P/Dopant: Boron; TIR <3 μm, TTV <10 μm, BOW <10 μm, Roughness <0.5 nm; Sizes Available: Four Inch 4'' Wafer with a Thickness of 525 µm +/- 20 µm; Formats Available: 1 Piece in a Wafer Carrier; 10 Pieces in a Wafer Box;25 Pieces in a Wafer Box; Wafer carriers or wafer boxes are included for every single purchase. 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.
