Latest Patents

Kai Xue holds a patent for a method titled "Method for removing electroplated metal facets and reusing a barrier layer without chemical mechanical polishing." This method aims to eliminate the need for chemical mechanical polishing (CMP) in the back end of line (BEOL) manufacturing processes. By employing electropolishing, the method effectively removes deposited surface metal while preserving the barrier layer. This results in a smooth surface suitable for subsequent manufacturing steps. The technique is particularly beneficial for the electropolishing of metal surfaces after the formation of filled vias in through-silicon via processes, utilizing metals such as copper, tungsten, aluminum, or their alloys. The remaining barrier layer can be reused to fabricate the redistribution layer, showcasing the method's efficiency and sustainability.
