By increasing the transistor topography after forming a first layer of
highly stressed dielectric material, additional stressed material may be
added, thereby efficiently increasing the entire layer thickness of the
stressed dielectric material. The corresponding increase of device
topography may be accomplished on the basis of respective placeholder
structures or dummy gates, wherein well-established gate patterning
processes may be used or wherein nano-imprint techniques may be employed.
Hence, in some illustrative embodiments, a significant increase of strain
may be obtained on the basis of well-established process techniques.
