Abstract:
In semiconductor devices, some active regions may frequently have to be formed on the basis of a silicon/germanium (Si/Ge) mixture in order to appropriately adjust transistor characteristics, for instance, for P-type transistors. To this end, the present disclosure provides manufacturing techniques and respective devices in which at least two different types of active regions, including Si/Ge material, may be provided with a high degree of compatibility with conventional process strategies. Due to the provision of different germanium concentrations, increased flexibility in adjusting characteristics of transistor elements that require Si/Ge material in their active regions may be achieved.

Claim (Index 1):
A method, comprising:\n exposing a first region and a second region of a crystalline silicon-containing semiconductor layer of a semiconductor device; forming a first crystalline silicon/germanium (Si/Ge) material in said first region, said first crystalline Si/Ge material having a first germanium concentration; forming a second crystalline Si/Ge material in said second region, said second crystalline Si/Ge material having a second germanium concentration that differs from said first germanium concentration; performing at least one oxidation process such that a post-oxidation first germanium concentration of said first crystalline silicon/germanium (Si/Ge) material is different from a post-oxidation second germanium concentration of said second crystalline Si/Ge material; and forming a first transistor element in and on said first region and forming a second transistor element in and on said second region.
