    摘要: A method and apparatus for automatic determination of semiconductor plasma chamber matching a source of fault are provided. Correlated plasma attributes are measured for process used for calibration both in a chamber under study and in a reference chamber. Principal component analysis then is performed on the measured correlated attributes so as to generate steady principle components and transitional principle components; and these principal components are compared to reference principal components associated with a reference chamber. The process used for calibration includes a regular plasma process followed by a process perturbation of one process parameter. Similar process perturbation runs are conducted several times to include different perturbation parameters. By performing inner products of the principle components of chamber under study and the reference chamber, matching scores can be reached. Automatic chamber matching can be determined by comparing these scores with preset control limits. The potential source(s) of chamber fault can also be identified by the lowest matching score(s).

    摘要: A method for automatic determination of a state of a substrate in a plasma processing chamber is provided. Substrate reflectance data is collected in a processing chamber prior to processing to be analyzed with reference reflectance data to determine if the substrate state meets a control criterion. The substrate state may define the thickness and the qualities of the films on the substrate, the critical dimensions of the different layers on the substrate. The reflectance data is analyzed using a multi-variant analysis technique, such as principle component analysis. In addition to analyzing substrate state prior to processing, substrate reflectance could also be collected in a processing chamber during processing to be analyzed with reference reflectance data to further determine if the substrate state and/or the substrate processing are meeting a control criterion.
