Abstract:
A method of fabricating a semiconductor device, having a reduced-oxygen copper-zinc alloy (Cuâ€”Zn) thin film formed on a copper (Cu) surface by electroplating the Cu surface in a chemical solution, comprising the steps of:forming a Cu surface on a semiconductor substrate; providing a chemical solution; electroplating the Cu surface in the chemical solution, thereby forming a Cuâ€”Zn alloy thin film on the Cu surface, wherein the Cuâ€”Zn alloy thin film completely covers the Cu surface; rinsing the Cuâ€”Zn alloy thin film in a solvent; drying the Cuâ€”Zn alloy thin film under a gaseous flow; annealing the Cuâ€”Zn alloy thin film formed on the Cu surface, thereby forming a reduced-oxygen Cuâ€”Zn alloy thin film; and completing formation of the semiconductor device.
