Abstract:
There is provided a plating apparatus for plating a rectangular substrate using a substrate holder holding the rectangular substrate. The plating apparatus comprises a plating bath configured to store the substrate holder holding the rectangular substrate, and an anode disposed inside the plating bath so as to face the substrate holder. The substrate holder includes an electrical contact configured to feed two opposite sides of the rectangular substrate. The rectangular substrate and the anode are placed inside the plating bath so as to satisfy the relationship of 0.59×L 1 −43.5 mm≤D 1 ≤0.58×L 1 −19.8 mm, where L 1  is the shortest distance between a substrate center of the rectangular substrate and the electrical contact, and D 1  is the distance between the rectangular substrate and the anode.

Claim (Index 4):
