    摘要： A superconducting field effect transistor which is very small in size and high in dimensional accuracy, has a first layer of material forming a control electrode and a second layer of another material is disposed on said first layer. A width of said first layer in a direction toward a superconducting source electrode and a superconducting drain electrode is narrower than a width of the second layer in the same direction. Polycrystalline silicon may be used as the control electrode while the second layer can be made of silicon nitride. Furthermore, a side surface of the control electrode may be coated with an insulator film. Accordingly, the above transistor has a fine structure gate electrode part that can be fabricated easily and accurately.
