    摘要: By incorporating a semiconductor species having the same valence and a different covalent radius compared to the base semiconductor material on the basis of an ion implantation process, a strain-inducing material may be positioned locally within a transistor at an appropriate manufacturing stage, thereby substantially not contributing to overall process complexity and also not affecting the further processing of the semiconductor device. Hence, a high degree of flexibility may be provided with respect to enhancing transistor performance in a highly local manner.

    摘要: Enhanced efficiency of a stress relaxation implantation process may be achieved by depositing a first layer of reduced thickness and relaxing the same at certain device regions, thereby obtaining an enhanced amount of substantially relaxed dielectric material in close proximity to the transistor under consideration, wherein a desired high amount of stressed dielectric material may be obtained above other transistors by performing a further deposition process. Hence, the negative effect of the highly stressed dielectric material for specific transistors, for instance in densely packed device regions, may be significantly reduced by depositing the highly stressed dielectric material in two steps with an intermediate relaxation implantation process.

    摘要: In sophisticated SOI devices, the thickness of the active semiconductor layer in the N-channel transistor may be reduced compared to the P-channel transistor for a given transistor configuration, thereby obtaining a significant increase in performance of the N-channel transistor without negatively affecting performance of the P-channel transistor.
