Latest Patents

Hwang's latest patents include a method for forming patterns in a semiconductor device. This innovative method enhances the contact area between a photoresist and an anti-reflective film by performing an etching process on the anti-reflective film. This process creates fine irregularities that help prevent the collapse of the photoresist pattern. The method involves several steps: first, forming an organic anti-reflective film by coating an organic anti-reflective coating composition and baking it. Next, fine irregularities are created on the organic anti-reflective film through etching. Finally, a photoresist pattern is formed by coating, exposing, and developing the photoresist on the organic anti-reflective film.

Another patent by Hwang focuses on forming patterns of a semiconductor device. This method inhibits the collapse of photoresist patterns during the pattern-forming processes. It achieves this by creating micro-bends in the anti-reflective film, which increases the contact area between the photoresist and the anti-reflective film. Additionally, it prevents critical dimension alteration of the photoresist pattern through double-laminating anti-reflective films with varying refractive indices and light-absorbencies.
