Abstract:
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.

Claim (Index 19):
A method, comprising:\n providing an apparatus comprising:\n a chuck configured to removeably hold a substrate for processing; \n an array of three or more ultrasonic sensors, each ultrasonic sensor of the three or more ultrasonic sensors configured to emit and detect ultrasonic sound waves, each ultrasonic sensor of the three or more ultrasonic sensors equally spaced from each other and arranged about a center of the chuck and positioned relative to the chuck so as to 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 of the substrate; \n a ceramic ring surrounding the chuck, wherein each ultrasonic sensor of the three or more ultrasonic sensors is notched into the ceramic ring, wherein a top surface of the ceramic ring is coplanar with a top surface of the chuck wherever on the ceramic ring there is a respective ultrasonic sensor of the three or more ultrasonic sensors, and wherein the top surface of the ceramic ring is coplanar with the top surface of the substrate wherever on the ceramic ring there is no ultrasonic sensor of the three or more ultrasonic sensors; and \n a controller; and \n placing the substrate on the chuck; and measuring a position of the substrate on the chuck using the array of three or more ultrasonic sensors and comparing, by the controller, the measured position to a specified position on the chuck.
