Claim Text:
1. A chip diode, comprising: a semiconductor substrate; a plurality of diode cells formed on the semiconductor substrate, each diode cell of the plurality of diode cells having an individual diode junction region; and parallel connection portions provided on the semiconductor substrate and connecting the plurality of diode cells in parallel, the parallel connection portions including a first electrode formed in one side of the semiconductor substrate and having at least two extending portions extending only to another side of the semiconductor substrate, wherein at least two diode junction regions are formed along each of the at least two extending portions, wherein at least two extending portions are formed to have line symmetry and at least four diode junction regions formed along the at least two extending portions are formed to have point symmetry and line symmetry in a plane view, and wherein each of at least the four diode junction regions has an outline and each outline has a line extending obliquely in a direction in which the extending portion extends in a plane view so that a space is formed in the center of at least the four diode junction regions.
