Abstract
It is very important to decompose uniformly the metal film in semiconductor devices process. The thickness uniformity of the ITO film by standard magnetron sputtering system are about $\pm4%\sim\pm5%$ and the center of the wafer is more thick than the edge of the wafer. We designed and made the discharge electrode structure and controlled the direction of sputtering materials in magnetron sputtering system. The thickness uniformity are increased to $\pm0.8\sim1.3%$ in 4" wafer using the new sputtering gun in magnetron sputtering system. In wafer to wafer thickness uniformity, $\pm$5.3% are increased to $\pm$1.5% using the new sputtering gun. The thickness uniformity of the Al film are about $\pm$1.0% using the new sputtering gun in magnetron sputtering system.
