Abstract
A manufacturing apparatus for a semiconductor device includes a substrate holding unit configured to hold a substrate; a processing liquid supply unit configured to supply a processing liquid onto the substrate held by the substrate holding unit; an electrolytic processing unit disposed to face the substrate holding unit and configured to perform an electrolytic processing on the substrate held by the substrate holding unit; and a terminal configured to apply a voltage to the substrate. The electrolytic processing unit includes a direct electrode configured to be brought into contact with the processing liquid supplied onto the substrate to apply a voltage with respect to the substrate; and an indirect electrode configured to form an electric field in the processing liquid supplied onto the substrate.
