    摘要: The present disclosure provides a method of fabricating a semiconductor device. The method includes forming a layer over a substrate. The method includes forming a first opening in the layer that exposes a first region of the substrate. The method includes removing a first oxidation layer formed over the first region through a first sputtering process. The method includes filling the first opening with a conductive material. The method includes forming a second opening in the layer that exposes a second region of the substrate, the second region being different from the first region. The method includes removing a second oxidation layer formed over the second region through a second sputtering process. One of the first and second sputtering processes is more powerful than the other.
