Title: Jim Schall: Innovator in Semiconductor Technology
Introduction
Jim Schall is a notable inventor based in Malalla, Oregon, who has made significant contributions to the field of semiconductor technology. With a total of 2 patents, he has developed innovative solutions that enhance the efficiency and effectiveness of semiconductor manufacturing processes.
Latest Patents
One of Jim's latest patents is a wafer chuck designed for use in edge bevel removal of copper from silicon wafers. This wafer chuck includes alignment members that allow a semiconductor wafer to be properly aligned on the chuck without the need for a separate alignment stage. The alignment members, which may be cams attached to the arms of the wafer chuck, assume an alignment position when a robot arm places the wafer on the chuck. This design ensures that the wafer is guided into the correct alignment position with respect to the chuck. During rotation at a specific speed, the alignment members move away from the wafer, allowing liquid etchant to flow over the entire edge region of the wafer. At higher rotational speeds, the wafer is clamped into position to prevent it from flying off the chuck, with a clamping cam or other device providing the necessary clamping.
