Abstract
A substrate processing device according to the present embodiment includes a processing tank configured to be capable of accumulating a liquid. A conveyer can array a plurality of semiconductor substrates in such a manner that front surfaces of the semiconductor substrates face a substantially horizontal direction, and transport the semiconductor substrates into the processing tank. A plurality of liquid suppliers can supply the liquid toward an inside of the processing tank from a lower portion of the processing tank. A plurality of current plates are arranged on at least either one end side or the other end side of an array of the semiconductor substrates. The current plates are provided in a first gap region above the semiconductor substrates in gaps between the conveyer and a sidewall of the processing tank on both sides of the conveyer as viewed from an array direction of the semiconductor substrates.
