Patent number: 10224225Abstract: An apparatus and an associated method. The apparatus includes a chuck, an array of three or more ultrasonic sensors, a ceramic ring surrounding the chuck, and a controller connected to the ultrasonic sensors. The chuck is configured to removeably hold a substrate for processing. Each ultrasonic sensor may send a respective ultrasonic sound wave to a respective preselected peripheral region of the substrate and receive a respective return ultrasonic sound wave from the preselected peripheral region. The controller may compare a measured position of the substrate on the chuck to a specified placement of the substrate on the chuck based on a measured elapsed time between sending the ultrasonic sound wave and receiving the return ultrasonic sound wave for each ultrasonic sensor. The method compares a measured position of the substrate on the chuck to a specified position on the chuck.Type: GrantFiled: April 19, 2018Date of Patent: March 5, 2019Assignee: International Business Machines CorporationInventors: Shawn A. Adderly, Samantha D. DiStefano, Jeffrey P. Gambino, Max G. Levy, Max L. Lifson, Matthew D. Moon, Timothy D. Sullivan
