Claim Text:
1. A plating equipment comprising: a jig holding a wafer to be plated at a center of a plating bath such that the wafer is vertically immersed into a plating solution in the plating bath; a first plating unit including a first plurality of anode members disposed on a first side of the plating bath facing the wafer, and a second plurality of anode members disposed on a second side of the plating bath facing the wafer, the first plating unit performing electroplating; and a second plating unit disposed in a light source receiving unit physically blocked from the first plating unit, the second plating unit being disposed behind the first plurality of anode members and the second plurality of anode members to perform light-induced plating by using a light emitting diode (LED) lamp irradiating light onto the wafer; wherein the first plurality of anode members and the second plurality of anode members are symmetrically disposed with respect to the wafer; wherein each member of the first plurality of anode members has a same width and is spaced apart at the same distance as a width of other members of the first plurality of anode members, and wherein each member of the second plurality of anode members has a same width and is spaced apart at the same distance as a width of other members of the second plurality of anode members.
