SPUTTERING SYSTEM AND METHOD FOR FORMING A METAL LAYER ON A SEMICONDUCTOR DEVICE
2019
A method for sputtering an aluminum layer on a surface of a semiconductor device is presented. The method includes three sputtering steps for depositing the aluminum layer, where each sputtering step includes at least one sputtering parameter that is different from a corresponding sputtering parameter of another sputtering step. The surface of the semiconductor device includes a dielectric layer having a plurality of openings formed through the dielectric layer.
