Abstract: PURPOSE:To eliminate a short circuit between wirings, migration, etc., by a method wherein wet etching is applied, after the lift-off, in the state wherein an electric field is impressed on a metal pattern, so as to etch only the portion of fluff selectively. CONSTITUTION:After a metal pattern is formed by the lift-off, a positive voltage is impressed on the metal pattern 5 from a power source 12, while a negative voltage is impressed on an opposite electrode 11 therefrom. In this state, a GaAs substrate 1 is immersed in an electrolyte 10, e.g., in a mixed solution of KCN, Na2HPO4, H2O when the metal is Au, and thus wet etching is conducted. By applying the wet etching in the state wherein an electric field is impressed on the metal pattern 5 on the GaAs substrate 1 in this way after the lift-off, the electric field is concentrated on the portion of sharp fluff 6 in the edge part of said metal pattern 5. Therefore, an etching rate in this portion turns high, and thus the fluff 6 is etched selectively. This method enables the attainment of the metal pattern 5 being free from the fluff 6 and excellent in quality, and the high-yield manufacture of a semiconductor device being free from faults such as migration and disconnection and highly reliable.
