Abstract: PURPOSE:To greatly contribute to practical use by forming an electron supply layer of two or more laminated layers, and constituting the electron supplying layers above the lowest layer, in the form corresponding with the channel shape of a one-dimensional electron gas. CONSTITUTION:By eliminating a part of a second electron supply layer, 2 DEG is turned into 1 DEG. In the region where only the first electron supplying layer 21 is left, electron in a channel layer 19 below the layer is depleted. After all, fine working is performed to obtain a form wherein lead wires 31 are connected to a ring shape 30 as a second electron supplying layer 22'. In addition, the end portions of both wires 31 are arranged so as to cover the upper layer of an impurity diffusion region 24. When the ring 30 whose line width is -0.1mum, and the lead 31 whose ring diameter is -1mum are formed by electron beam lithography and the like, electron gas exists only in the ring 30 of the layer 22' and just under the lead wires 31, and an interference ring of one-dimensional electron gas is formed because the line width is narrow. By this constitution, the decrease of the coherence length is not caused even if working defect for one-dimensional performance is present. As a result, great contribution is obtained to the practical use of a ultra high speed semiconductor device using electron wave.
