Latest Patents

One of Qingchen Cao's latest patents is focused on the "Openings layout of three-dimensional memory device." This patent discloses embodiments of semiconductor devices and methods for forming these devices. The method involves forming a material layer over two adjacent regions of a substrate, followed by the creation of a mask layer and a patterning layer that includes openings corresponding to the first region. Notably, the size of the first opening is greater than that of the second opening along a plane parallel to the substrate's top surface.

Another significant patent is the "Method and structure for cutting dense line patterns using self-aligned double patterning." This patent outlines a method for forming a semiconductor structure that includes the formation of mandrel lines and the use of dielectric spacers. The process involves creating blocked regions and forming openings through the first dielectric layer, ultimately leading to the formation of objective lines that are coplanar with the top surfaces of the first dielectric layer.
