Publication number: 20250104982Abstract: An apparatus comprises a vacuum chamber with a processing zone, an RF generator, a sensor, and a controller. The vacuum chamber is configured to receive process gas for a plasma-based process of a substrate. The RF generator provides an RF signal between a first electrode and a second electrode of the vacuum chamber to generate plasma for the plasma-based process. The sensor is configured to sense at least one signal characteristic of the RF signal. The controller is configured to retrieve during the plasma-based process, a plurality of signals from the sensor. The plurality of signals is indicative of the at least one signal characteristic of the RF signal at a corresponding plurality of time instances. The controller determines an endpoint for the plasma-based process based on the plurality of signals from the sensor. The controller terminates the plasma-based process based on the endpoint.Type: ApplicationFiled: July 20, 2022Publication date: March 27, 2025Inventors: Gordon Alex MacDonald, Ragesh Puthenkovilakam, Todd Schroeder, Chin-Jui Hsu, Sagar Balagangadhara Udyavara, Kapu Sirish Reddy, Yukinori Sakiyama

Publication number: 20250028620Abstract: Systems and methods are disclosed that relate to applications and platforms for performing in-system testing for autonomous or semi-autonomous systems and applications. In some embodiments, resources of a computing system may be grouped into one or more subsets of system elements (e.g., “a chiplet”) and may be configured to be controlled via an associated local controller, which may enable and/or disable the chiplet as targeted. In embodiments, the local controllers may receive instructions from a central controller and, via the enabling and/or disabling of the chiplets, may maintain a number of resources consumed during system testing within a threshold. As a result, the system may be configured to perform system testing without additional resources and/or without redirecting resources that may be intended for other operations.Type: ApplicationFiled: July 17, 2023Publication date: January 23, 2025Inventors: Shantanu SARANGI, Milind SONAWANE, Alex HSU, Sailendra CHADALAVADA, Nitin YOGI, Nithin VALENTINE

Patent number: 10756627Abstract: A switch mode power supply (voltage converter) is adapted as a current-mode control buck regulator for different loading conditions. The voltage converter operates in a continuous conduction mode (CCM) during heavy load conditions using pulse width modulation (PWM). When a zero-current detector determines no inductor current during light load conditions (discontinuous conduction mode (DCM) region), the controller initiates adaptive duty control using pulse frequency modulation (PFM). Adaptive duty estimation circuitry provides controllable energy to charge the power inductor to maintain voltage accuracy and maximize efficiency when in the PFM mode. Using clock synchronization and a single control-loop, smooth transition between PFM, PWM, and bypass modes is automatically performed. Clock synchronization from a master oscillator provides a base for frequency division in different operation modes which gives controllable evenly distributed switching harmonics.Type: GrantFiled: September 11, 2018Date of Patent: August 25, 2020Assignee: MICROCHIP TECHNOLOGY INCORPORATEDInventors: Alex Hsu, Sam Tsui, Paolo Nora, Tsz Yin Man
