| titleOfInvention | Actively preserving solution for electroless copper plated film |
| abstract | PURPOSE: To enable an electroless copper plated film to be preserved at an active state for a long time with an actively preserving soln. by precipitating a slight amt. of copper from divalent copper ions in the soln. by reduction and attaching the copper to the film. n CONSTITUTION: An actively preserving soln. contg. divalent copper ions, a cuprous ion sequestering agent and hypophosphite is set to the pH range of 2.5W4.5. A source for the copper ions includes copper sulfate and cupric chloride, and the ion concn. is desirably adjusted to 0.01mol/l or more. As the sequestering agent a cpd. having an oxycarboxylic acid group, e.g., sodium citrate can be utilized. n COPYRIGHT: (C)1980,JPO&Japio |
