Patent ID: 7332198

Claim:
A plating method, comprising: plating a workpiece in a plating apparatus by allowing a surface to be plated of the workpiece to be in contact with a plating solution, the plating apparatus including; (i) a plating bath having a double bath structure including an inner bath for holding the plating solution and for carrying out said plating, and an outer bath which surrounds the inner bath and is in fluid communication therewith; (ii) a heating device disposed in the outer bath so as to heat the plating solution; (iii) a blending system for circulating or stirring the plating solution in the plating bath, the blending system being operable to stop functioning during plating of the workpiece; and (iv) a holder for holding a workpiece so that a surface of the workpiece to be plated faces downward, and for rotating the workpiece; stopping the functioning of the blending system during said plating; and rotating the workpiece during said plating using the holder in a manner to counteract a natural convection of the heated plating solution so as to bring the plating solution into a stationary state during said plating.
