摘要：
A method of manufacturing a semiconductor device, comprising the following processes of forming a structure in which a barrier metal containing at least of Ti and Ta and a copper wiring are exposed on its surface, or a structure in which at least one substance selected from the group consisting of Ti, W, and Cu and Al are exposed on its surface, above a semiconductor. substrate, and supplying a hydrogen-dissolved solution dissolving hydrogen gas to the surface of the structure.
