Latest Patents

Among Rigsby’s latest innovations is a patent titled "Process for optimizing cobalt electrofill using sacrificial oxidants." This groundbreaking technology pertains to methods, apparatus, and systems designed for electroplating metals into recessed features. The superconformal fill mechanism featured in this patent allows for faster plating within the feature while maintaining slower plating in the surrounding field region. Notably, this mechanism ensures that plating occurs more rapidly towards the bottom of the feature compared to the top, achieving a superior fill quality without the complications of seams or voids—a common issue in traditional conformal filling methods. The presence of a sacrificial oxidant molecule aids in creating a differential current efficiency conducive to optimal plating conditions, thereby enhancing the overall effectiveness. Importantly, the method can operate without organic plating additives, though such additives may be used to further improve the process.
