Latest Patents

One of his latest patents is titled "Method for forming a field oxide film in a semiconductor device." This method involves several steps, including the sequential formation of a pad oxide film and a first buffer silicon nitride film on a silicon substrate. A patterned mask is then created, followed by etching to expose parts of the pad oxide film. The process continues with the formation of a buffer oxide film and additional layers, ultimately leading to the formation of a field oxide film through thermal oxidation. This innovative approach minimizes the size of the bird's beak generated during the formation of the field oxide film.

Another significant patent by Sang I Kim is "Method for removing residual material from a cavity during the manufacture of a partially completed multi-layer semiconductor device." This method addresses the challenge of removing residual material that remains in a cavity after an anisotropic etching process. Utilizing a plasma etching apparatus, the etchable layer is first etched until the top of the etch-stop layer is exposed. A plasma scattering etching process is then performed to effectively remove the residual material from the cavity.
