Title: The Innovations of Takahito Fukushima
Introduction
Takahito Fukushima is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of semiconductor technology, holding three patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is a spread spectrum clock generating circuit. This invention includes a delay circuit that has input terminals, which delays a signal input from each terminal by different delay times. The circuit outputs the delayed signal from at least one output terminal. Additionally, it features a selective circuit that receives an input clock signal and selectively outputs the clock signal to one of the input terminals of the delay circuit. A control circuit switches the selective operations of the selective circuit, resulting in a modulated clock signal with an increased or decreased period.
Another significant patent is for a semiconductor integrated circuit having an anti-fuse, along with methods for fabricating and writing data in the same. This semiconductor integrated circuit contains a first MOS transistor of a first conductivity type formed on the surface of a semiconductor substrate. It also includes a second MOS transistor of the same conductivity type, which has a lower drain-source breakdown voltage than the first. The second MOS transistor serves as an anti-fuse, capable of being changed to a conductive state with a low writing voltage that does not damage the first MOS transistor.
