Latest Patents

Rob Stoya holds a patent for "Methods for chemical mechanical planarization and for detecting endpoint of a CMP operation." This patent outlines methods for chemical mechanical planarization of a layer and for determining the endpoint of a CMP operation. The method involves making a plurality of eddy current thickness measurements of the layer being planarized, with each measurement spaced apart by a predetermined length of time. A difference is calculated between sequential measurements, and a predetermined minimum threshold for the difference is established. The endpoint is defined as a calculated difference that is less than the predetermined minimum threshold. This innovative approach enhances the precision of CMP processes.
