Patent number: 8274645Abstract: A method and apparatus for in-situ metrology of a workpiece disposed in a vacuum processing chamber. The apparatus may include an optical assembly external to the processing chamber configured to focus a relatively large optical spot over a relatively large working distance to acquire a TE and TM spectra from a periodic array on the workpiece. The workpiece may be disposed in the processing chamber with an arbitrary orientation which is first determined via a reflectance measurement. TE and/or TM spectra may then be acquired by initiating a periodic triggering of a flash lamp based on the determined workpiece orientation to account for variation in placement of the workpiece within the processing chamber. The periodic array from which spectra are collected may be a memory array being fabricated in a semiconductor wafer.Type: GrantFiled: July 20, 2009Date of Patent: September 25, 2012Assignee: Applied Materials, Inc.Inventors: Matthew F.

Patent number: 7695987Abstract: 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 principal components and transitional principal 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 principal 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.Type: GrantFiled: December 19, 2006Date of Patent: April 13, 2010Assignee: Applied Materils, Inc.Inventors: Matthew F.
