Latest Patents

One of her latest patents is a method to improve isolation layer fill in a DRAM array area. This innovative approach involves forming gate conductor lines for a DRAM during the manufacturing process of integrated circuit devices. The method includes defining active areas on a semiconductor substrate, depositing a gate conductor layer, and patterning it to create gate conductor lines. The intersections of these lines and the active areas form DRAM transistors. The technique ensures that adjacent gate conductor lines are spaced differently in critical and non-critical regions, which helps to reduce the aspect ratio in non-critical areas, ultimately preventing shorts without compromising transistor performance.

Another significant patent is the anisotropic formation process of oxide layers for vertical transistors. This method focuses on forming a thin oxide layer on the circumferential wall of a trench while simultaneously creating a thick oxide layer on the bottom surface. The thick oxide layer acts as the trench top oxide, while the thin oxide layer serves as the gate oxide, enhancing the overall efficiency of vertical transistors.
