Latest Patents

One of his latest patents is a method of fabricating a semiconductor device. This method includes forming plugs in a semiconductor device that connect an upper conductive layer to a lower conductive layer without the need for contact holes. The process involves defining an active area of a device, forming a gate oxide, and creating a plurality of gates along a specific direction. Additionally, an impurity region is formed in the active area, and sidewall spacers are created at the sides of the gates. The method culminates in the formation of plugs that contact the impurity region, enhancing the device's functionality.

Another notable patent is a method for patterning a chemical amplification photoresist. This method involves applying a photoresist film on a semiconductor substrate and exposing it to light. The substrate is then subjected to an alkaline gas, which removes undesired hydrogen ions from non-exposure portions of the photoresist. This innovative approach prevents the formation of unnecessary patterns, thereby improving the reliability of semiconductor devices.
