  • Patent number: 7102737
    Abstract: A method and apparatus for detection of a particular material, such as photo-resist material, on a sample surface are disclosed. A narrow beam of light is projected onto the sample surface and the fluoresced and/or reflected light intensity at a particular wavelength band is measured by a light detector. The light intensity is converted to a numerical value and transmitted electronically to a logic circuit, which determines the proper disposition of the sample. The logic circuit controls a sample-handling robotic device which sequentially transfers samples to and from a stage for testing and subsequent disposition. The method is particularly useful for detecting photo-resist material on the surface of a semiconductor wafer.

  • Patent number: 6287927
    Abstract: In one aspect, the invention includes a method of thermal processing comprising: a) providing a semiconductor substrate, the semiconductor substrate supporting a material that is to be thermally processed; b) forming a sacrificial mass over the material, the mass comprising an inner portion and an outer portion, the inner portion having a different composition than the outer portion and being nearer the material than the outer portion; c) exposing the mass to radiation to heat the mass, the exposing being for a period of time sufficient for the material to absorb heat from the mass and be thermally processed thereby; and d) removing the mass from over the material.
