SEMICONDUCTOR DEVICE SUPPLYING CHARGING CURRENT TO ELEMENT TO BE CHARGED |
摘要 |
A semiconductor device supplying a charging current to a charging-target element includes: a semiconductor layer of a first conductivity type; a first semiconductor region of a second conductivity type formed on a main surface of the semiconductor layer and having a first node coupled to a first electrode of the charging-target element and a second node coupled to a power supply potential node supplied with a power supply voltage; a second semiconductor region of the first conductivity type formed in a surface of the first semiconductor region at a distance from the semiconductor layer and having a third node coupled to the power supply potential node; and a charge carrier drift restriction portion restricting drift of charge carrier from the third node to the semiconductor layer.
