Claim Text:
1. A longitudinal bidirectional device in which current flows in a layering direction of a semiconductor layered portion formed on a front surface of a substrate, the bidirectional device comprising: a first semiconductor element that includes a first channel and is formed on the semiconductor layered portion; and a second semiconductor element that includes a second channel and is provided on the substrate side of the first semiconductor element within the semiconductor layered portion, wherein the first semiconductor element further includes a first control electrode that controls the first channel and that is formed on a surface of the semiconductor layered portion that faces away from the substrate, the second semiconductor element is formed on at least a portion of the surface of the semiconductor layered portion on which the first control electrode is formed and includes a second control electrode that controls the second channel, the first channel is formed according to a first voltage that is applied to the first control electrode, and the second channel is formed according to a second voltage that is applied to the second control electrode.
