Abstract: The cylinder includes a core and a coating covering most of the core. The core is made from a heat-resistant or insulating material. The core has inner and outer side walls and opposing first and second ends. The outer side wall is further away from a central longitudinal axis of the cylinder than the inner wall. The first end is configured to contact an edge ring that supports a semiconductor substrate. The coating is substantially opaque to infrared radiation, and covers all external surfaces of the core except for the first end. The core is preferably made from quartz or ceramics, while the coating is preferably made from a polysilicon.

Abstract: In a system for thermal processing of a semiconductor substrate, a reflector plate has a stepped surface facing the substrate during heating and cooling of the substrate. The raised surface of the reflector plate has reduced reflectivity, providing advantages during, among other things, cooling of the substrate. The reflector plate also includes a number of recesses to which one or more pyrometers are coupled. These recesses have a highly reflective surface, providing advantages in the performance of the pyrometers.

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 is capable of producing a stream of least 70% ozone. The ozone passes into an RTP chamber through a water-cooled injector projecting into the chamber. Other gases such as hydrogen to increase oxidation rate, diluent gas such as nitrogen or O2, enter the chamber through another inlet. 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 including a pedestal heater and a showerhead gas injector in opposition to the pedestal.
