  • Publication number: 20050037615
    Abstract: A method for processing a workpiece and an associated processing chamber and analytic instrument. A layer of a material such as a low-K dielectric is applied to a workpiece such as a semiconductor wafer. During the application, and/or before or during subsequent processing, a property of the layer is measured by steps including exciting a portion of the layer with incident light and monitoring light such as Raman scattered light that is emitted from that portion of the layer in response to the incident light, via a probehead that may be inside or outside the chamber housing. The analytic instrument includes the probehead and two sources of excitation light at two different wavelengths.

  • Patent number: 5856871
    Abstract: A method of determining the thickness map of a film (14) overlying a substrate (14). This method includes illuminating (10) the film simultaneously from different angles and analyzing spectral intensity of the radiation reflected by each point on the film (14). The analysis is effected by collecting reflected radiation from the film (14), passing the radiation through an interferometer (16) which outputs modulated radiation corresponding to a predetermined set of linear combinations of the spectral intensity of the radiation emitted from each pixel, simultaneously and separately scanning optical path differences generated in the interferometer (16) for each pixel, focusing the radiation outputted from the interferometer (16) on a detector array, and processing the output of the detector array to determine the spectral intensity of each pixel thereof to obtain a spectral intensity distribution.

  • Patent number: 5823681
    Abstract: An emissivity compensating non-contact system for measuring the temperature of a semiconductor wafer. The system includes a semiconductor wafer emissivity compensation station for measuring the reflectivity of the wafer at discrete wavelengths to yield wafer emissivity in specific wavelength bands. The system further includes a measurement probe which is optically coupled to a semiconductor process chamber. The probe senses wafer self emission using one or more optical detectors and a light modulator. A background temperature determining mechanism independently senses the temperature of a source of background radiation. Finally, a mechanism calculates the temperature of the semiconductor wafer based on the reflectivity, self-emission and background temperature.
