Abstract
PURPOSE:To make it possible to manufacture easily a superconducting transistor, by applying a usual light exposure, by using a structure having a two-dimensional electron gas system stored in an undoped semiconductor layer wherein the band gap of a hetero junction boundary surface is small. CONSTITUTION:A nondoped GaAs layer 2 of 5000Angstrom thick, a nondoped Al0.3Ga0.7 As spacer layer 3 of 150Angstrom thick, and an Si doped N-type A0.3Ga0.7As layer 4 are formed in order on a semiinsulative GaAs substrate 1. A source electrode 15 and a drain electrode 16 composed of superconductor formed of an Nb thin film are formed, and a gate electrode 7 composed of Al is formed. A sidewall 8 formed of SiN separates a gate electrode 7 from the source and drain electrodes 15, 16. The semiconductor layer has a so-called selection doping hetero-structure. In the hetero-boundary surface, two-dimensional electron gas 20 is formed, wherein electron supplied from an N-type AlGaAs layer is stored.
