    摘要: In sophisticated semiconductor devices, an asymmetric transistor configuration may be obtained on the basis of an asymmetric well implantation while avoiding a tilted implantation process. For this purpose, a graded implantation mask may be formed, such as a graded resist mask, which may have a higher ion blocking capability at the drain side compared to the source side of the asymmetric transistor. For instance, the asymmetric configuration may be obtained on the basis of a non-tilted implantation process with a high degree of performance gain and may be accomplished irrespective of the technology standard under consideration.
