PROBLEM TO BE SOLVED: To provide an anodization apparatus suitable for automatization and a batch process, and having a mechanism by which a substrate is held, transferred, and made into a part of an anodization tank, and a semiconductor substrate having a porous layer formed.SOLUTION: A plurality of substrates W are moved to a processing position while held by a left holder part 67 and a right holder part 69, and connected to an upper holder part 71 and a lower holder part 39, and then the whole circumferential surfaces of the plurality of substrates W are liquid-tight with an electrolyte solution in a reservoir 11. In this state, anodization processing is performed, and then the substrates W are discharged from the reservoir 11. Thus, the left holder part 67 and the right holder part 69 are structured along with the upper holder part 71 and the lower holder part 39 so as to be able to hold the substrates W in a liquid-tight state. Therefore, the anodization apparatus 1 suitable for automatization and a batch process is achieved, by which the plurality of the substrates W are transferred, and porous layers are formed. Also, according to the apparatus, the semiconductor substrate including porous layers efficiently and uniformly formed on both surfaces, the front and rear surfaces, can be provided.
