Latest Patents
One of Dongsheng Liu's notable patents is titled "Reduced ESR in trench capacitor." This patent describes a method of fabricating an integrated circuit that includes etching trenches in a first surface of a semiconductor layer. A trench dielectric layer is formed over the first surface and over the bottoms and sidewalls of the trenches. A doped polysilicon layer is then formed over the trench dielectric layer and within the trenches. The doped polysilicon layer is patterned to create a polysilicon bridge that connects to the polysilicon within the filled trenches. A blanket implant of a first dopant is directed to the polysilicon bridge and to the first surface, forming a contact region that extends from the first surface into the semiconductor layer. This innovative approach has the potential to improve the efficiency and performance of integrated circuits.
