Latest Patents

Yi-Kun Chen's latest patents include innovative methods for semiconductor device fabrication. The first patent, titled "Semiconductor device and fabrication method thereof," outlines a process that begins with the provision of a first dummy gate, which includes a first high-k gate insulator layer, a first composite sacrificial layer, and a first dummy gate electrode. The method involves removing the first dummy gate electrode to expose the first composite sacrificial layer, followed by its removal. Subsequently, a first work function layer is formed on the first high-k gate insulator layer, culminating in the formation of a first metal gate electrode.

The second patent, "Semiconductor structure and fabricating method thereof," describes a method for fabricating a semiconductor structure. This process starts with a substrate that has a dielectric layer with openings exposing portions of the substrate. A gate dielectric layer, consisting of a high-k dielectric layer and a barrier layer, is formed at the bottoms of these openings. A sacrificial layer is then added, followed by the formation of a first work function metal layer. The method concludes with the removal of specific portions of the first work function metal layer and the sacrificial layer.
