Latest Patents

One of Takaoki Sasaki's latest patents is a method of manufacturing a semiconductor device. This invention involves forming a gate insulating film and a gate electrode on a silicon substrate. The gate insulating film contains hafnium, oxygen, fluorine, and nitrogen. Notably, the fluorine concentration is high near the interface with the silicon substrate and decreases progressively as the distance from the gate electrode increases. Similarly, the nitrogen concentration is high near the interface with the gate electrode and decreases as the distance from the silicon substrate increases. The patent specifies that the fluorine concentration in the vicinity of the interface with the silicon substrate should be at least 1×10 cm or more, while the nitrogen concentration near the gate electrode should also be at least 1×10 cm or more.

Another significant patent involves an authentication system, which includes a signing station and a certifying station. In this system, the signing station divides the data to be transmitted into multiple segments, and a hash unit creates authenticators by applying different one-way functions to each segment. The certifying station also divides the data and compares the newly prepared authenticators with those separated from the received data to verify the authenticity of the data.
