Publication number: 20240128131Abstract: A camera may capture reflected light from the surface of the wafer during a semiconductor process that adds or removes material from the wafer, such as an etch process. To accurately determine an endpoint for the process, a camera sampling rate and light source intensity may be optimized in the process recipe. Optimizing the light source intensity may include characterizing light intensities that will be reflected from the waiver using an image of the wafer. Pixel intensities may be used to adjust the light source intensity to compensate for more complex wafer patterns. Optimizing the camera sampling rates may include nondestructively rotating a view of the wafer and converting the sampled intensities to the frequency domain. The camera sampling rate may be increased or decreased to remove spatial noise from the image without oversampling unnecessarily. These optimized parameters may then generate a clean, repeatable trace for endpoint determination.Type: ApplicationFiled: October 14, 2022Publication date: April 18, 2024Applicant: Applied Materials, Inc.Inventors: Avishay Vaxman, Qintao Zhang, Jeffrey P.

Patent number: 9911249Abstract: A method for operating a diagnostic system of a vehicle including a fail operational power system (FOPS) module and a fail operational system (FOS) module includes the FOS module requesting a microcontroller of the FOPS module to generate a diagnostic control signal. The FOS module receives the diagnostic information from a component module of the FOPS module based on the diagnostic control signal generated by the microcontroller. The FOS module executes isolator diagnostics based on the received diagnostic information.Type: GrantFiled: September 3, 2013Date of Patent: March 6, 2018Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: David P. Koch, Chandra S. Namuduri, Jeffrey James Hoorn, Nikhil L. Hoskeri, Mark C. Hoinka

Patent number: 9440600Abstract: Method for operating a fail operational power system for a vehicle includes monitoring voltages on first and second power distribution paths arranged in parallel. Each path includes a respective first or second isolator switch effective when operative in a closed state to power the respective path by a respective energy storage device for supplying electrical power to one or more loads partitioned on each of the paths. A third isolator switch controllably operative between open and closed states is monitored. The closed state of the third isolator switch connects the paths and the open state opens the connection between the paths. When a predetermined operating mode requiring fail operational power is enabled, the third isolator switch is controlled to the open state when at least one of the monitored voltages violates a reference voltage and is controlled to the closed state when neither one of the monitored voltages violate the reference voltage.Type: GrantFiled: September 3, 2013Date of Patent: September 13, 2016Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: David P.

Patent number: 9184582Abstract: Method for operating a fail operational power system for a vehicle includes monitoring a first voltage on a first power distribution path and a second voltage on a second power distribution path. An isolator switch controllably operative between open and closed states is monitored. The closed state connects the first and second power distribution paths and the open state opens the connection between the first and second power distribution paths. Each of the monitored first and second voltages is compared to a reference voltage. When a predetermined operating mode requiring fail operational power is enabled, the isolator switch is controlled to the open state when at least one of the monitored first and second voltages violates the reference voltage and the isolator switch is controlled to the closed state when neither one of the monitored first and second voltages violates the reference voltage.Type: GrantFiled: September 3, 2013Date of Patent: November 10, 2015Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: David P.
