Latest Patents
One of Wan-Chi Wu's latest patents is related to dynamic random access memory. This innovation includes a first bit line extending along a first direction, a first buried word line extending along a second direction, and an active region that overlaps part of both the first bit line and the first buried word line. The active region is designed in a V-shape, enhancing the efficiency of the DRAM. Additionally, the DRAM features at least one storage node contact that overlaps one end of the active region, with the storage node contact shaped as an ellipse.
Another significant patent involves a manufacturing method for an epitaxial contact structure in a semiconductor memory device. This method includes several steps, starting with the formation of a recess in a semiconductor substrate through an etching process. An etching defect is created during this process, followed by an oxidation process that forms an oxide layer in the recess, encompassing the etching defect. A cleaning process is then performed to remove both the oxide layer and the etching defect, leading to the formation of an epitaxial contact structure through an epitaxial growth process.
