A method for fabricating a junction barrier Schottky diode device is disclosed. The junction barrier Schottky device includes an N-type semiconductor layer, a plurality of first P-type doped areas, a plurality of second P-type doped areas, and a conductive metal layer. The first P-type doped areas and the second P-type doped are formed in the N-type semiconductor layer. The second P-type doped areas are self-alignedly formed above the first P-type doped areas. The spacing between every neighboring two of the second P-type doped areas is larger than the spacing between every neighboring two of the first P-type doped areas. The conductive metal layer, formed on the N-type semiconductor layer, covers the first P-type doped areas and the second P-type doped areas.
