LPCVD Processes


LPCVD refers to a thermal process used to deposit thin films from gas-phase precursors at subatmospheric pressures. Process conditions are typically selected so that the growth rate is limited by the rate of the surface reaction, which is temperature-dependent. The temperature can be controlled with great precision, resulting in excellent within-wafer, wafer-to-wafer, and run-to-run uniformities.
