    摘要: The field effect transistor comprises a substrate successively comprising an electrically conducting support substrate, an electrically insulating layer and a semiconductor material layer. The counter-electrode is formed in a first portion of the support substrate facing the semi-conductor material layer. The insulating pattern surrounds the semi-conductor material layer to delineate a first active area and it penetrates partially into the support layer to delineate the first portion. An electrically conducting contact passes through the insulating pattern from a first lateral surface in contact with the counter-electrode through to a second surface. The contact is electrically connected to the counter-electrode.

    摘要: The field effect device comprises a sacrificial gate electrode having side walls covered by lateral spacers formed on a semiconductor material film. The source/drain electrodes are formed in the semiconductor material film and are arranged on each side of the gate electrode. A diffusion barrier element is implanted through the void left by the sacrificial gate so as to form a modified diffusion area underneath the lateral spacers. The modified diffusion area is an area where the mobility of the doping impurities is reduced compared with the source/drain electrodes.
