Latest Patents

Hannafin holds a patent for a polishing article specifically designed for electro-chemical mechanical polishing. This invention includes an electrically-conductive compound formed into a layer. The compound is an admixture that consists of a polymeric component forming a continuous phase and an electrically-conductive filler component creating a discrete phase within the continuous phase. The workpiece and the layer are electrically connected, with an electrical bias applied between them. This bias activates an electrochemical reaction, allowing the compound to exhibit an overpotential for the activation of the reaction greater than the bias. He has 1 patent to his name.
