Latest Patents

Owada's latest patents include a groundbreaking semiconductor device featuring a rewritable nonvolatile memory cell. This device comprises a first field effect transistor for memory, along with circuits that include a second and third field effect transistor. Each transistor is designed with a gate insulating film formed over a semiconductor substrate, a gate electrode positioned above the gate insulating film, and sidewall spacers on the sides of the gate electrode. Notably, the sidewall spacers of the first field effect transistor differ from those of the second field effect transistor. Additionally, the gate insulating film of the third field effect transistor is thicker than that of the second, and its gate electrode has a length that varies from the other transistors. The sidewall spacers of the first field effect transistor consist of a first silicon oxide film, a first silicon nitride film over the silicon oxide, and a second silicon oxide film on top of the nitride film.

Another significant patent involves a method for manufacturing a semiconductor device that forms a rewritable nonvolatile memory cell. This method includes creating a gate insulating film over a semiconductor substrate, placing a gate electrode above the insulating film, and adding sidewall spacers to the gate electrode of each field effect transistor. The width of the sidewall spacers for the first field effect transistor is different from that of the second, while the gate electrode of the third field effect transistor has a different length compared to the first. The gate insulating film of the third field effect transistor is also thicker than that of the second.
