Latest Patents
One of his latest patents is a semiconductor device having a fuse and protection circuit. This invention features a semiconductor substrate, an insulating layer, a fuse, a diffusion layer, and a resistor. The semiconductor substrate has a first conductivity type, while the insulating layer is selectively formed on its surface. The fuse is positioned on the insulating layer, and the diffusion layer, which has a second conductivity type, is formed on the substrate and electrically connected to the fuse. Additionally, the first resistor is electrically connected to the fuse.
Another notable patent is a method of manufacturing non-volatile read-only memory. This method enables the production of a mask ROM for storing quaternary data, allowing for a short turnaround time and simplifying the refinement of cell sizes. Gaps are formed between word lines in the memory cell transistors and two diffusion areas based on quaternary write data. A current flows between these diffusion areas only when one of them, adjacent to a gap, is used as a drain. This innovative approach allows for quaternary data to be read efficiently.
