Abstract
The present invention provides a technique that enables the formation of a recessed spacer element by using an anisotropically deposited etch stop layer. Accordingly, in subsequent cleaning processes, material residues of the etch stop layer may be efficiently removed from upper sidewall portions of a line element, thereby increasing the available area for a diffusion path in a subsequent silicidation process. The anisotropic deposition of the etch stop layer may be accomplished by high density plasma enhanced CVD or by directional sputter techniques.
