Latest Patents
One of his latest patents is titled "Semiconductor device having trench isolation layer and a method of forming the same." This invention provides a semiconductor device that includes a trench isolation layer in a semiconductor substrate. The trench isolation layer consists of a silicon nitride liner, a silicon oxide liner, and a buried layer. The buried layer is designed to fill both the lower and upper parts of the trench isolation layer. Additionally, the semiconductor device features a silicon oxide layer positioned between the semiconductor substrate and the silicon nitride liner, which includes a thermal oxide layer densified at temperatures exceeding 800°C.
Another notable patent is "Structure of trench isolation and a method of forming the same." This invention addresses the formation of trench isolation for both wide and narrow trenches in a substrate. It ensures that no voids, grooves, or electrical bridges occur during the isolation process. The method involves forming a lower isolation layer on the substrate in both trenches, which is then patterned to fill the lower region of the first trench while an upper isolation pattern fills the second trench and the remainder of the first trench. This innovative approach reduces the aspect ratio of the first trench, preventing voids in the upper isolation layer.
