A multi-polar insulated gate transistor having two or more isolated electrodes formed on an insulated film, and an island region having a conductivity type different from that of the semiconductor proper and located in the portion of the substrate beneath said film and below the gap between said electrodes, whereby a large current can flow through the element located closer to the drain when the respective elements which may consist of the pair, i.e., each gate and source-island, island-island or island-drain are under identical voltage conditions. |
