Abstract:
1. A method of forming one or more conductive structures for an integrated circuit, the method comprising: providing a solution including at least one surfactant and at least one metal, with the solution having a surfactant concentration; and forming an insulative structure having at least one hole and at least one trench, with the at least one hole having a sidewall portion; depositing the at least one metal and the at least one surfactant from the solution into the at least one hole; removing at least a portion of the at least one surfactant from the at least one hole or the at least one trench to form a diffusion barrier after depositing the at least one metal and the at least one surfactant; and depositing metal in the at least one trench after removing at least a portion of the at least one surfactant.
