Latest Patents

Among his latest patents, one is titled "Method for fabricating flash memory." This invention describes a process where a stacked gate structure and a source/drain are formed on a substrate. An inter-layer dielectric and multiple inter-metal dielectric layers are then created over the substrate. Notably, at least one layer among these dielectrics includes a silicon carbide layer, which serves to protect the memory device from UV irradiation, thereby preventing data errors. Another significant patent is "Method for forming flash memory cell." This method outlines a series of steps starting with the provision of a substrate, followed by the formation of a gate dielectric layer, a first polysilicon layer, and a hard mask layer. The process includes removing portions of these layers to create holes that expose the substrate, followed by the formation of a dielectric layer in those holes using a HDPCVD process.
