    摘要: A residue-free plasma etch of high temperature aluminum copper metallization is provided by the use of a single plasma etcher. The metallization layer is covered by a protective oxide layer. This structure is then placed in the single etcher and a vacuum is established. The protective oxide layer is then etched and without breaking the vacuum or removing the structure from the etcher the metal layer is also etched. This results in the etched surface being residue-free.

    摘要: A method for forming a semiconductor device includes forming a liner over a semiconductor material including a control electrode. The method further includes forming a first spacer adjacent to the control electrode, wherein the first spacer has a first width. The method further includes implanting current electrode dopants. The method further includes removing the first spacer. The method further includes forming a second spacer adjacent the control electrode, wherein the second spacer has a second width and wherein the second width is less than the first width. The method further includes using the second spacer as a protective mask to selectively remove the liner. The method further includes forming a stressor layer overlying the control electrode and current electrode regions.
