摘要:
A plating bath which accommodates an insoluble node and a printed-circuit board, and a copper dissolved bath which supplies copper ions are arranged. The insoluble anode Is arranged as opposed to the printed-circuit board being a cathode, and a forward/reverse current is applied between both of the electrodes. Iron ions are added to a plating solution.
摘要:
An aqueous solution containing sulfuric acid and hydrogen peroxide is used for a soft etchant in a soft etching step in a smear removing process performed prior to a catalyst applying process for chemical copper plating after formation of via holes through an insulating layer of a multi-layer substrate by irradiation of laser. The concentration of sulfuric acid is 2.4 times or less than the concentration of hydrogen peroxide. Preferably, the concentration of sulfuric acid is in a range of 9 to 90 g/l, and the concentration of sulfuric acid is lower than the concentration of hydrogen peroxide. More preferably, the concentration of sulfuric acid is in a range of 9 to 18 g/l, and the concentration of hydrogen peroxide is in a range of 33 to 38.5 g/l. As a result, smear can be certainly removed without excessively etching a conductive layer in the smear removing process.

In an in-liquid plasma film-forming apparatus having: a vessel 1 being capable of accommodating a substrate “S” and a liquid “L” including raw material therein; an electrode 2 for in-liquid plasma, electrode 2 which is disposed in the vessel 1; an electric power device 3 for supplying electricity to the electrode 2 for in-liquid plasma; the electrode 2 for in-liquid plasma is equipped with: a main electrode 21 having a discharging end 22; an auxiliary electrode 26 not only facing the discharging end 22 but also being disposed between the discharging end 22 and the substrate “S” that face each other; and a plasma generating unit 29 having a space that is demarcated by a surface 22a of the discharging end 22 and a surface 26a of the auxiliary electrode 26 facing the surface 22a, and being for generating plasma by means of electricity being supplied to the main electrode 21. And, a decomposed component of the raw material is deposited onto a surface of the substrate “S” by contacting the plasma, which has generated at the plasma generating unit 29, with the substrate “S.”By means of the present construction, it becomes feasible to generate plasma in liquid without ever using a second electrode that serves as a substrate.
