Deep drain and source regions of an N-channel transistor may be formed through corresponding cavities, which may be formed together with cavities of a P-channel transistor, wherein the lateral offsets of the cavities may be adjusted on the basis of an appropriate reverse spacer regime. Consequently, the dopant species in the N-channel transistor extends down to a specific depth, for instance down to the buried insulating layer of an SOI device, while at the same time providing an efficient strain-inducing mechanism for the P-channel transistor with a highly efficient overall manufacturing process flow. |
