Alpha Nanotech Prime-Grade 4'' Silica Wafer (525 um Silicon and 300 nm Silica) (25)

Description

🔬 Elevate your innovation with wafers engineered for perfection

The Alpha Nanotech Prime-Grade 4'' Silica Wafer features a 525 µm thick CZ Virgin silicon substrate with a 200 nm dry oxide layer, polished front surface, and etched back surface. It offers tight flatness tolerances (TIR < 3 μm, TTV & BOW < 10 μm) and ultra-smooth surface roughness below 0.5 nm, with a P/Boron dopant resistivity range of 1 - 30 ohm·cm, making it ideal for high-precision semiconductor manufacturing.
