Latest Patents

Among his latest patents is a method for flattening epitaxial semiconductor wafers. This process involves preparing an epitaxial wafer with a total thickness variation of less than about 1.0 µm. The method includes measuring the distance between the front and back surfaces of the wafer to generate thickness profile data. Additional stock is then removed from the front surface to achieve the target thickness, T.sub.t, based on the thickness profile data.

Another significant patent is related to controlling the flatness of polished semiconductors. This apparatus determines the flatness of a circular polishing pad through direct measurement. It includes a measuring device and a frame that allows for measuring the distance between the pad's upper surface and a reference plane at multiple locations. The controller indicates whether the flatness of the pad meets predetermined specifications.
