Abstract:
Fabrication of a microelectronic device comprising a semiconductor structure provided with semiconductor bars positioned above one another, the method comprising the following steps: creating, on a substrate, a stacked structure comprising an alternation of first bars containing a first material and having a first critical dimension and second bars ( 14 2 , 14 4 , 14 6 ) containing a second material, the second material being a semiconductor, the second bars having a second critical dimension greater than the first critical dimension, then, surface doping protruding lateral portions ( 15 ) of the second bars before formation of a source and drain block on these portions.

Claim (Index 1):
A method for fabricating a microelectronic device with at least a transistor comprising a semiconductor structure provided with semiconductor bars positioned above one another, the method comprising the following steps:\n forming, on a substrate, a stacked structure comprising an alternation of one or more first bars of a first material and one or more second bars of a second material, the second material being a semiconductor, the second bars comprising lateral portions protruding with respect to the lateral portion(s) of the first bar(s), then, surface doping the lateral portions of the structure, then forming insulating inner spacers against the first bar(s), the forming of insulating inner spacers comprising depositing a dielectric material layer on the stacked structure then etching the dielectric material, the method further comprising, during etching of the layer of dielectric material or after etching of the dielectric material layer; a removal of a material thickness at the side face of the protuding lateral portions and so as to reveal end regions of the second semiconductor bars based on the second material, then forming source and drain blocks via growth of semiconductor material at regions of ends of said lateral portions.
