The sulfuric acid acidic copper electrolyte and the electrodeposition copper membrane which are manufactured making use of the manufacturing method and the said manufacturing method of the sulfuric acid acidic copper electrolyte

摘要

It uses the chemicals of mono sulfide type with this case invention, vis-a-vis the copper electrolyte, as the additive from immediately after the building bathing it is smooth and offer of the sulfuric acid acidic copper electrolyte whose it is possible to obtain the electrodeposition copper membrane which is superior in glossy characteristic stably is designated as purpose. Bis (3 sulfonic propyl) it uses disulfide in order to achieve this purpose, in the sulfuric acid acidic copper electrolyte which adds the sulfonate of the active sulfur chemical compound which is proposed to the one for formation of the electrodeposition copper membrane which possesses gloss, as the additive. This bis (3 sulfonic propyl) disulfide can bis (3 sulfonic propyl) making 3 merukaputo 1 propane sulfonic acid disulfide convert from the aqueous solution of 3 merukaputo 1 propane sulfonic acid, with the oxidation reaction. In order to prevent the oxidation disassembly of 3 merukaputo 1 propane sulfonic acid, it is desirable in the oxidation reaction of this time to use air babbling method.
