Latest Patents

Among her latest patents, Young-Hun Seo has created a method and apparatus to form gates in semiconductor devices. This patented method involves forming a gate oxide layer and a sacrificial layer on a semiconductor substrate. After selectively etching the sacrificial layer to create a sidewall opening, she then forms a polycrystalline silicon layer on the exposed gate oxide area and the sacrificial layer. The process is completed with anisotropic etching to create sidewall gates that align with the desired dimensions of a gate. The sacrificial layer is subsequently removed, following the etching of the polycrystalline silicon layer.

Another significant advancement from Seo is her method of forming a trench in a semiconductor device using a polish stop layer and an anti-reflection coating. This method includes the formation of a polish stop layer on a semiconductor substrate, which is then etched alongside the substrate to create a trench at a specific depth. The process meticulously rounds the ends of the polish stop layer adjacent to the trench before forming an insulation layer that fills the trench, ensuring optimal performance of the semiconductor devices.
