Latest Patents

Simmons holds a patent for a low particulate vacuum chamber input/output valve. This invention minimizes particulate generation during the operation of semiconductor wafer processing. The valve employs a camming motion at the moment of closing, ensuring that it closes perpendicular to the reaction chamber wall. This design eliminates friction between the glandular seal and the vacuum chamber wall. As the valve closes, it strikes a stop, causing a 90-degree change in direction that forces it into a tape cut. This mechanism is achieved through a combination of an upper motion of a backing plate and a spring-loaded linkage. Although some particulate is generated at the interface of the valve plate and the stop, this is managed by positioning the contact area outside the transportation path for the semiconductor wafer.
