Latest Patents
Renteln's latest patents include innovative methods and apparatuses for controlling polishing pad conditioning. One patent describes a method for determining the amount of conditioning required to be applied to a polishing pad to achieve a desired removal rate during the polishing of a semiconductor wafer. This method utilizes a rotating conditioning wheel in contact with a rotating polishing pad. Preselected points on polished wafers are measured for removal rate, and these measurements are used to calculate the removal rate as a function of wafer radius. When the removal rate changes by a preselected amount, the polishing pad is conditioned according to these calculations. His other patent focuses on a polishing pad and method for polishing semiconductor wafers. This polishing pad includes a polishing layer and a rigid layer, which imparts controlled rigidity to the polishing layer. The resilient layer adjacent to the rigid layer provides uniform pressure, allowing the polishing layer to conform to the wafer surface's global topography while maintaining controlled rigidity over the local topography.
