Latest Patents

David A. Pechin holds a patent for an "Apparatus for aligning substrate to chuck in processing chamber." This invention features a passive mechanism designed to center a wafer on a chuck with respect to a backside exclusion gas ring. The apparatus includes a series of wheels that are rotatably mounted in a circular pattern on the chuck's top surface. The design allows the wafer to self-center due to its weight, as it contacts the wheels upon placement. This innovative mechanism either allows the wafer to slide on the wheels or causes the wheels to turn if the frictional force is sufficient. The alignment wheels can be mounted on various components, including a carrier ring or a wafer transfer arm.
