Abstract

A MOS transistor manufacturing method, including: forming a first conductive or semiconductor layer; forming a sacrificial gate on the first layer and a second layer made of an insulating material laterally surrounding the sacrificial gate; forming, on either side of the sacrificial gate, source and drain electric connection elements crossing the second layer and contacting the first layer; removing the sacrificial gate and the portion of the first layer located vertically in line with the sacrificial gate; depositing a third layer made of a two-dimensional semiconductor material; depositing a fourth layer made of an insulating material on the third layer; and forming a conductive gate in the opening, on the fourth layer.
