Latest Patents

Kevin holds a patent for a "System for detecting a film layer on an object." This invention utilizes circularly polarized light to determine the end point of a thin film layer. The process involves passing collimated light through a polarizing filter and a polarizing beam splitter, resulting in light that is predominantly linearly polarized in a specific direction. This light is then converted to circularly polarized light using a quarter wave retarder. Upon reflecting off a surface with a thin film layer, the circularly polarized light passes back through the quarter wave retarder, where it is transformed into linearly polarized light with a different direction. This second direction of polarized light can be easily isolated and analyzed by end-point detection circuitry, allowing for accurate detection of the film layer's end point.
