| description | PROBLEM TO BE SOLVED: To provide a sputtering method which uses an ionized thin-film forming substance. SOLUTION: A sputtering method using an ionized thin-film forming substance comprises a metallization step for forming a barrier layer, a resistor layer and an interconnection layer through sputtering. In this case, a primary deposited film 106 is formed using a sputtering system with on ac power applied to a semiconductor substrate having an arbitrary film formed thereon, and a secondary deposited film 108 is then formed with the ac power continuously applied thereto. As a result, damages to the surface of the semiconductor substrate can be suppressed, and step coverage characteristic is improved. |
