Abstract:
1. A manufacture comprising an integrated circuit comprising a semiconductor substrate, logic gates, and a memory, said logic gates comprising FDSOI-type transistors made on said substrate, including at least one first transistor comprising a gate with a first work function, and including at least one second transistor comprising a gate with a second work function distinct from said first work function, said memory including a plurality of memory cells, each memory cell comprising FDSOI type transistors, wherein at least one third transistor is an nMOS transistor that comprises a gate presenting a third work function, a buried insulating layer, and a ground plane separating said buried insulating layer from said substrate, and wherein at least one fourth transistor is a pMOS transistor that comprises a gate presenting said third work function, a buried insulating layer, and a ground plane separating said buried insulating layer from said substrate, said ground planes of said third and fourth transistors having common doping, being made in a well separating said ground planes from said substrate, and being adapted to be biased in the same way.
