INTEGRATED CIRCUIT ON SOI HAVING TRANSISTORS WITH SEPARATE THRESHOLD VOLTAGES

摘要

The invention relates to an integrated circuit including an active semiconducting layer separated from a semiconducting substrate layer by an embedded insulating material surface, including: first and second transistors (205, 213) of a single type; first and second floorplans arranged vertically perpendicular to the first and second transistors; wherein the first transistor has a doping of the floorplan thereof, opposite that of the source thereof, and a first threshold voltage; the second transistor has a doping of the floorplan thereof, identical to that of the source thereof, and a second threshold voltage; the first threshold voltage is dependent on the potential difference applied between the source and the floorplan of the first transistor; and the second threshold voltage is dependent on the potential difference applied between the source and the floorplan of the second transistor.
