Latest Patents

Andrew Kuswatno holds a patent for a "Method of Shallow Trench Isolation." This invention presents an improved process for forming isolations of uniform thickness in both narrow and wide trenches. The process begins with the formation of a pad layer on a semiconductor substrate, followed by the creation of a first barrier layer. The substrate is then etched to form shallow trenches, which are categorized into narrow and wide trenches based on their widths. The invention also includes the growth of a thin oxide film and a gap-fill dielectric layer, along with a polysilicon layer that provides additional protection during chemical mechanical polishing (CMP). The final steps involve oxidizing the polysilicon layer to form a novel second dielectric oxide layer, ensuring uniform thickness in the trenches.
