摘要: Methods and systems for determining a radial differential metrology profile of a substrate heated in a process chamber is provided. Methods and systems for determining an angular or azimuthal differential metrology profile of a rotating substrate in a processing chamber are also provided. The radial and azimuthal differential metrology profiles are applied to adjust a reference metrology profile to provide a Virtual metrology of the process chamber. The virtual metrology is applied to control the performance of the process chamber.

摘要: Methods and apparatus for measuring substrate uniformity is provided. The invention includes placing a substrate in a thermal processing chamber, rotating the substrate while the substrate is heated, measuring a temperature of the substrate at a plurality of radial locations as the substrate rotates, correlating each temperature measurement with a location on the substrate, and generating a temperature contour map for the substrate based on the correlated temperature measurements. Numerous other aspects are provided.
