<p>The present invention provides a copper electroplating method using an insoluble anode, including: using an insoluble anode and a copper electroplating solution which contains a compound having a -X-S-Y- structure (where X and Y are each independently selected from the group consisting of a hydrogen atom, a carbon atom, a sulfur atom, a nitrogen atom, and an oxygen atom, and X and Y can be the same only where they are carbon atoms); and using direct current to plate a substrate. By this method, even a certain time period after the initial make-up of the electrolytic bath, stable deposition of the plated metal and formation of a filled via can be achieved, and an MVH can be filled up with the metal with no void left. <IMAGE></p> |
