Silicon Oxidation

Thermal Oxidation of Silicon

CMOS-compatible quartz furnace processes (Centrotherm), try and wet oxidation 100 and 150mm wafer size, batch quantity: up to 50 wafers per run.

LOCOS oxide (LPCVD nitride mask layer)
Gate Oxide, standard thickness 40 nm

Cusomized Oxide layers possible, thickness range 10 nm up to 1500 nm

thickness non-uniformity across wafer: <2%
average thickness non-uniformity wafer-to-wafer: <3%
average thickness non-uniformity batch-to-batch: <5%
