Abstract
In a semiconductor device, a first semiconductor layer is formed on a semiconductor substrate. A second semiconductor layer is formed on a part of the first semiconductor layer, and a third semiconductor layer is formed on a part of the second semiconductor layer. A first electrode is formed on the third semiconductor layer, and a second electrode is formed on the first semiconductor layer in contact with the second semiconductor layer and apart from the semiconductor layer, thus forming a diode.
