    Abstract: A method for selective deposition of Si or SiGe on a Si or SiGe surface exploits differences in physico-chemical surface behavior according to a difference in doping of first and second surface regions. By providing at least one first surface region with a Boron doping of a suitable concentration range and exposing the substrate surface to a cleaning and passivating ambient atmosphere in a prebake at a temperature lower or equal to 800° C., a subsequent deposition step will prevent deposition in the first surface region. This allows selective deposition in the second surface region, which is not doped with the Boron (or doped with another dopant or not doped). Several devices are, thus, provided. The method saves a usual photolithography sequence, which according to prior art is required for selective deposition of Si or SiGe in the second surface region.

  • Patent number: 8021942
    Abstract: In the process sequence for replacing conventional gate electrode structures by high-k metal gate structures, the number of additional masking steps may be maintained at a low level, for instance by using highly selective etch steps, thereby maintaining a high degree of compatibility with conventional CMOS techniques. Furthermore, the techniques disclosed herein enable compatibility to front-end process techniques and back-end process techniques, thereby allowing the integration of well-established strain-inducing mechanisms in the transistor level as well as in the contact level.
