Latest Patents: Wen Chuan Chiang holds a patent titled "Method to reduce contact hole aspect ratio for embedded DRAM arrays and logic devices." This patent presents a method for reducing the high aspect ratios encountered when forming and filling narrow diameter contact holes in thick insulator layers. The method features a two-step contact hole opening and filling procedure. Initially, lower narrow diameter contact holes are opened in the lower levels of insulator layers and filled with tungsten. After the deposition of upper levels of insulator layers, upper narrow diameter contact holes are formed, exposing the tungsten-filled lower diameter contact holes. A second tungsten layer fills the upper narrow diameter contact hole, resulting in a final narrow diameter contact hole in thick insulator layers, formed with reduced aspect ratios through the two contact hole openings and tungsten fill procedures.
