Patent number: 7969465Abstract: The invention provides a substrate surface imaging method and apparatus that compensates for non-linear movement of the substrate surface during an imaging sequence. In one aspect of the invention, the imaging method and apparatus compensate for the non-linear substrate surface movement by adjusting the image receiver trigger points to correspond to image positions on the substrate surface. In another aspect, the invention provides synchronous imaging where the distance between each image position is determined by counting the number of stepper motor steps between image positions. In still another aspect, the invention provides for asynchronous substrate imaging by determining an image trigger time between each image position and using the image trigger time to trigger the receiver at the appropriate time to accurately image the substrate surface.Type: GrantFiled: December 19, 2006Date of Patent: June 28, 2011Assignee: Applied Materials, Inc.Inventors: Don T. Batson, Reginald Hunter

Patent number: 6882416Abstract: The present invention generally provides an apparatus and a method for inspecting a substrate in a processing system. In one aspect, a light source is used in conjunction with an optical receiving device, such as a camera having a CCD, to illuminate and inspect a substrate for various optical signatures. The data collected during an inspection cycle is processed to determine substrate topography information. In one embodiment, the data is used to generate mean values indicative of signal intensity and/or color. One aspect provides for specular signature analysis where a reference histogram is subtracted from a test substrate histogram. The mean values are then compared to reference values to determine topographical conditions. Advantageously, a data processing system may be used to collect the data, perform the specular signature analysis, and determine the resultant processing conditions.Type: GrantFiled: October 6, 2000Date of Patent: April 19, 2005Assignee: Applied Materials, Inc.Inventors: Reginald Hunter, Eduardo Marquis

Patent number: 6878636Abstract: Embodiments of the invention generally provide a method for enhancing chemical reactions within a substrate processing chamber during a substrate processing sequence. The method generally includes supporting a substrate in a face up position on a substrate support member, providing a process gas into the processing chamber, and striking a plasma of the process gas. The method further includes imparting at least one impulse to the substrate support member that is substantially perpendicular to a substrate surface, the at least one impulse being of sufficient magnitude to agitate the substrate surface to expand an exposed surface area of the substrate surface.Type: GrantFiled: June 12, 2002Date of Patent: April 12, 2005Assignee: Applied Materials, Inc.Inventors: Joel Brad Bailey, Reginald Hunter

Patent number: 6813032Abstract: The present invention generally provides an apparatus and a method for inspecting a substrate in a processing system. In one aspect, a par of light sources is used in conjunction with an optical receiving device, such as a camera having a CCD, to illuminate and inspect a substrate for various optical signatures. The substrate signatures are then used to generate images of obstructions in three dimensions (3-D) for further analysis. In one embodiment, the substrate is scanned in two or more directions with a first light source and then scanned in two or more directions with a second light source. A receiver captures the reflected and/or scatted signals from sources comprising two or more different images. The light illumination from the first and second light sources impinges on substrate surface obstructions from two differing angles (i.e. perspectives).Type: GrantFiled: October 6, 2000Date of Patent: November 2, 2004Assignee: Applied Materials, Inc.Inventor: Reginald Hunter
