Abstract: PURPOSE:To remove an influence of the surface including a surface level and to prevent a short channel effect from being caused by a method wherein an ohmic electrode is applied to an arsenic-doped gallium arsenide layer on a plane 100 and it is used as a source electrode and a drain electrode. CONSTITUTION:An n-type GaAs layer 2 and an n<+> type GaAs layer 3 are formed one after another on a gallium arsenide (GaAs) substrate 1 having a plane 100 by a molecular beam epitaxial method; then, a groove having a V-shaped mesa shape having a plane 111A is formed by using an etching solution. Then, an epitaxial layer 4 is formed on the plane 110 and a plane 100 by the molecular beam epitaxial method. During this process, a P-type GaAs layer 4a is grown on the plane 110 and an n-type GaAs layer 4b is grown on the plane 100. A gate electrode 5, a source electrode 6 and a drain electrode 7 are formed on the epitaxial layer formed in this manner. Thereby, an influence of an irregularity in a mesa shape and a mesa depth on a characteristic can be reduced.
