Abstract
A semiconductor device is disclosed, which comprises a first main electrode, a second main electrode, a high-resistance semiconductor layer of first conductivity type interposed between the first main electrode and the second main electrode, and at least a buried layer of second conductivity type selectively formed in the semiconductor layer, extending at substantially right angles to a line connecting the first and second main electrodes, comprising a plurality strips functioning as current paths and set at a potential different from a potential of any other electrode when a depletion layer extending from a region near the first main electrode reaches the buried layer.
