摘要:
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.

摘要:
A method for rapid thermal annealing is disclosed. As the substrate is inserted into an annealing chamber, it begins to heat due to the heat radiating from chamber components that were heated when a previous substrate was annealed. Thus, the leading edge of the substrate may be at an elevated temperature while the trailing edge of the substrate may be at room temperature while the substrate is inserted causing a temperature gradient is present across the substrate. Once the substrate is completely inserted into the annealing chamber, the temperature gradient may still be present. By compensating for the temperature gradient across the substrate, the substrate may be annealed uniformly.

In one embodiment, the invention is directed to an apparatus for preventing depositions from occurring on a reflector in a processing chamber, comprising: a cover disposed adjacent to the reflector, the cover optically transparent over a range of wavelengths in which the reflector is reflective; and at least one cover support for maintaining the position of the cover relative to the reflector.
摘要:
A method of reducing stress on a substrate in a thermal processing chamber. The method includes the steps of supporting a first portion of a substrate by means of contacting the same such that a second portion of the substrate is not contacted, part of the second portion forming one wall of a cavity, and flowing a gas into the cavity such that the pressure of the gas exerts a force on the second portion to at least partially support the second portion.
摘要:
An interferometer system and method may be used to measure substrate thickness or shape. The system may include two spaced apart reference flats having that form an optical cavity between two parallel reference surfaces. A substrate holder may be configured to place the substrate in the cavity with first and second substrate surfaces substantially parallel with corresponding first and second reference surfaces such that a space between the first or second substrate surface is three millimeters or less from a corresponding one of the reference surfaces or a damping surface. Interferometer devices may be located on diametrically opposite sides of the cavity and optically coupled thereto. The interferometers can map variations in spacing between the substrate surfaces and the reference surfaces, respectively, through interference of light optically coupled to and from to the cavity via the interferometer devices.

A method for controlling the temperature of a substrate in a processing chamber. The processing chamber employs a heating control over at least two heating zones. Each heating zone is independently controllable according to a measured signal corresponding to the substrate temperature and a user-definable offset.
