Latest Patents

One of his latest patents is related to a flash memory with a trench common source line. This invention includes a substrate, control gates, trenches, source regions, isolation structures, drain regions, a common source line, floating gates, tunneling dielectric layers, and a dielectric layer. The design features control gates and trenches oriented in different directions on the substrate. The source regions are strategically placed in the substrate and trenches adjacent to the control gates. Isolation structures fill the trenches between the source regions, while drain regions are located on the opposite side of the control gates. The common source line is integrated within the substrate and connects electrically to the source regions. Additionally, floating gates are positioned between the control gates and the substrate, with tunneling dielectric layers situated between the floating gates and the substrate, and a dielectric layer between the floating and control gates.

Another significant patent by Chen is a planarization method using anisotropic wet etching. This method is designed to planarize an insulating layer with an uneven surface on a substrate. The etching solution is created by mixing H SO, H PO, HF, and H O. The substrate is immersed in this solution, allowing it to flow over the insulating layer at a controlled rate to achieve the desired etching effect. After a specified etching duration, the insulating layer attains a more planar surface.
