Claim Text:
1. A semiconductor structure comprising: a substrate; a first transistor and a second transistor, said first transistor being one of a P-channel transistor and an N-channel transistor, said second transistor being the other of a P-channel transistor and an N-channel transistor; at least one electrically conductive pillar positioned above said substrate and comprising a first inner portion and a first outer layer that is provided below said first inner portion and lateral to first said inner portion; and a first gate electrode structure for said first transistor positioned above said substrate and comprising a second inner portion and a second outer layer that is provided below said second inner portion and lateral to said second inner portion, wherein said first gate electrode structure annularly encloses each of said at least one electrically conductive pillar, said first outer layer contacts said second outer layer and said first outer layer and said second outer layer are formed of different metallic materials.
