Latest Patents

One of Gregory Kearns' latest patents is titled "Wafer shielding for prevention of lipseal plate-out." This invention addresses the undesired deposition of metals on a lipseal during the electrodeposition of metals on semiconductor substrates. By minimizing or eliminating ionic current directed at a lipseal, Kearns' method effectively reduces or eliminates lipseal plate-out. The process involves shielding a selected zone near the lipseal to suppress electrodeposition of metal, ensuring that metal does not contact the lipseal. In some embodiments, different inner diameters of lipseals are used during electroplating to enhance this shielding effect.

Another notable patent is the "Cross flow conduit for foaming prevention in high convection plating cells." This invention relates to apparatuses and methods for electroplating materials onto a substrate. Kearns' design utilizes a cross flow conduit in the electroplating cell to divert fluid flow from a region between the substrate and a channeled ionically resistive plate. This innovative approach helps manage overflow fluid and ensures efficient recirculation within the plating system.
