Latest Patents

Ji-Hong Choi's latest patents focus on methods of forming integrated circuit devices that incorporate metal diffusion barrier layers. These methods involve creating an interlayer insulating layer with a trench on a substrate, where an electrical interconnect, such as a copper damascene interconnect, is formed. The process includes recessing the upper surface of the insulating layer to expose the sidewalls of the interconnect. An electrically insulating first capping pattern is then formed on the recessed surface and the exposed sidewalls, while being removed from the upper surface of the interconnect. A metal diffusion barrier layer is subsequently formed on the upper surface of the interconnect, with the first capping pattern preventing the barrier layer from forming on the sidewalls. This innovative approach may utilize an electroless plating technique.
