Latest Patents

Among his latest patents is a method and apparatus for electrochemical planarization of a workpiece. This invention features an electrochemical planarization apparatus designed to planarize a metallized surface on a workpiece. The apparatus includes a polishing pad and a platen made of conductive material, which is configured to have a negative charge during the planarization process. The design incorporates an electrical conductor connected to a power source, allowing for the creation of an electric potential difference that facilitates the removal of the metallized surface from the workpiece.

Another significant patent by Emesh involves filling deep features with conductors in semiconductor manufacturing. This method describes a process for filling a conductive material in a three-dimensional integration feature on a wafer's surface. The feature can be lined with dielectric and/or adhesion/barrier layers before being filled with a liquid mixture containing conductive precursors. The substrate is rotated during the application of the mixture, and the liquid carrier is subsequently dried, leaving a conductive layer in the feature. This process can be repeated until the feature is fully filled, followed by annealing to form a dense conductive plug.
