Publication number: 20240038601Abstract: An electronic device manufacturing system including a substrate-holder configured to secure a substrate during processing and a controller, operatively coupled to the substrate-holder. The controller is configured to apply, to an electrode of the substrate-holder, a first voltage. The controller is further configured to determine a first impedance value between the substrate-holder and the substrate. The controller is further configured to determine a delta value between the first impedance value and a predetermined second impedance value, and determine whether the delta value satisfies a threshold criterion. Responsive to the delta value failing to satisfy the threshold criterion, the controller is further configured to apply a second voltage to the substrate, wherein the second voltage is greater than the first voltage.Type: ApplicationFiled: July 28, 2022Publication date: February 1, 2024Inventors: Mitesh Sanghvi, Venkatanarayana Shankarmurthy, Abdul Aziz Khaja

Patent number: 11841692Abstract: A method includes identifying a recipe for depositing layers on a substrate in a processing chamber of a substrate processing system. The recipe comprises iterations of a set of one or more processes, and wherein each iteration of the iterations is for depositing at least one layer of the layers. The method further includes determining changes to parameters for depositing the at least one layer on the substrate. Each of the changes corresponds to a respective iteration of the iterations and is associated with a relative position of a corresponding layer. The layers are to be deposited on one or more substrates based on the recipe and the changes.Type: GrantFiled: September 16, 2022Date of Patent: December 12, 2023Assignee: Applied Materials, Inc.Inventors: Venkatanarayana Shankaramurthy, Anton Baryshnikov, Brett Berens, Mitesh Sanghvi, Shuang Liu

Publication number: 20230359179Abstract: An electronic device manufacturing system capable of obtaining metrology data associated with a deposition process performed on a substrate according to a process recipe, wherein the deposition process generates a plurality of layers on a surface of the substrate. The manufacturing system can further obtain an expected profile associate with the process recipe, wherein the expected profile comprises a plurality of values indicative of a desired thickness for a plurality of layers of the process recipe. The manufacturing system can further generate a correction profile based on the metrology data and the expected profile, wherein the correction profile comprises a deposition time offset value for at least one layer of the plurality of layers. The manufacturing system can further generate an updated process recipe by applying the correction profile to the process recipe and cause a deposition step to be performed on the substrate according to the updated process recipe.Type: ApplicationFiled: May 5, 2022Publication date: November 9, 2023Inventors: Mitesh Sanghvi, Venkatanarayana Shankarmurthy, Yulian Yao, Chuan Ying Wang, Xinhai Han

Patent number: 11714430Abstract: A method includes identifying time values for a length of time to carry out process fluid delivery within multiple processing chambers that concurrently process multiple substrates; translating each time value to a recipe parameter for execution of an operation of a processing recipe; and causing the operation to be performed using each recipe parameter as a control value to control valves of a fluid panel of the multiple processing chambers. For each processing chamber of the multiple processing chambers, selectively controlling process fluid flow to the process chamber for a first period of time corresponding to a time value of the set of time values and to a divert foreline of the process chamber for a second period of time.Type: GrantFiled: September 29, 2022Date of Patent: August 1, 2023Assignee: Applied Materials, Inc.Inventors: Mitesh Sanghvi, Venkatanarayana Shankaramurthy, Peter Standish, Anton Baryshnikov, Thorsten Kril, Chahal Neema, Vishal Suresh Jamakhandi, Abhijit Ashok Kangude
