Latest Patents

Morriyama holds a patent for a semiconductor device utilizing junction leak current. This innovative design involves forming a first well of a first conductivity type in a partial region of the surface layer of a semiconductor substrate. A MOS transistor is created within this first well, featuring a gate insulating film, a gate electrode, and first and second impurity diffusion regions of a second conductivity type on either side of the gate electrode. The structure is designed to achieve a high leak current, resulting in a leak current density that is greater when a reverse bias voltage is applied across the first impurity diffusion region and first well compared to the second impurity diffusion region and first well.
