Title: William H. Jarvi: Innovator in Wafer Positioning Technology
Introduction
William H. Jarvi is a notable inventor based in San Jose, California. He has made significant contributions to the field of semiconductor processing, particularly through his innovative work on wafer positioning systems. With a total of 2 patents, Jarvi has demonstrated his expertise and commitment to advancing technology in this critical area.
Latest Patents
One of Jarvi's latest patents is a wafer positioning system designed to determine the position of a wafer during processing. This system monitors the position of the wafer transport robot as it moves the wafer using one or more position sensors. The innovative design incorporates a transparent cover on the surface of the wafer handling chamber, along with two optical position sensors positioned on the cover. These sensors direct light through the chamber to reflectors located near the floor, which reflect the light back to the sensors. A detector within the position sensor identifies when the beam path to the reflector is uninterrupted. As wafers are transported, the edge of the wafer interrupts the beam path, causing the sensor output to switch states. This allows for precise measurement of the wafer transport robot's position. If the wafer is misaligned, the robot's position is adjusted accordingly to ensure optimal processing.
