Latest Patents

Among her latest inventions is the patent for a "Process for optimizing cobalt electrofill using sacrificial oxidants." This groundbreaking method revolves around electroplating metal into recessed features through a superconformal fill mechanism. This mechanism ensures that plating occurs faster at the bottom of a feature compared to its top, achieving a high-quality fill that eliminates seams and voids—common defects associated with traditional conformal fill methods. The technique utilizes a sacrificial oxidant molecule to maintain differential current efficiency, allowing for balanced plating conditions to ensure effective filling from the bottom upwards. Notably, organic plating additives are rendered unnecessary, although their use is permitted to enhance the process.
