Technique for forming a transistor having raised drain and source regions with a tri-layer hard mask for gate patterning |
摘要 |
By providing a hard mask layer stack including at least three different layers for patterning a gate electrode structure, constraints demanded by sophisticated lithography, as well as cap layer integrity, in a subsequent selective epitaxial growth process may be accomplished, thereby providing the potential for further device scaling of transistor devices requiring raised drain and source regions.
