Abstract: A method and apparatus for oxidizing materials used in semiconductor integrated circuits, for example, for oxidizing silicon to form a dielectric gate. An ozonator (134) is capable of producing a stream of least 70% ozone. The ozone passes into an RTP chamber (10) through a water-cooled injector (140) projecting into the chamber. Other gases such as hydrogen to increase oxidation rate, diluent gas such as nitrogen or O 2 , enter the chamber through another inlet (122) . The chamber is maintained at a low pressure below 20 Torr and the substrate is advantageously maintained at a temperature less than 800°C. Alternatively, the oxidation may be performed in an LPCVD chamber (210) including a pedestal heater (230) and a showerhead gas injector (220) in opposition to the pedestal (216).
