    摘要： In a P-channel transistor comprising a high-k metal gate electrode structure, a superior dopant profile may be obtained, at least in the threshold adjusting semiconductor material, such as a silicon/germanium material, by incorporating a diffusion blocking species, such as fluorine, prior to forming the threshold adjusting semiconductor material. Consequently, the drain and source extension regions may be provided with a high dopant concentration as required for obtaining the target Miller capacitance without inducing undue dopant diffusion below the threshold adjusting semiconductor material, which may otherwise result in increased leakage currents and increased risk of punch through events.

    摘要： A self-aligned well implantation process may be performed so as to adjust threshold voltage and/or body resistance of transistors. To this end, after removing a placeholder material of gate electrode structures, the implantation process may be performed on the basis of appropriate process parameters to obtain the desired transistor characteristics. Thereafter, any appropriate electrode metal may be filled in, thereby providing gate electrode structures having superior performance. For example, high-k metal gate electrode structures may be formed on the basis of a replacement gate approach, while the additional late well implantation may provide a high degree of flexibility in providing different transistor versions of the same basic configuration.
