Abstract: A microelectronic device includes a plurality of disconnected similar semiconducting portions, electrically isolated from each other and forming a semiconductor layer, at a spacing by a constant distance and with a shape parallel to the other portions. The microelectronic device also includes two electrodes arranged in contact with the semiconductor layer such that a maximum distance separating the two electrodes is less than the largest dimension of one of the semiconductor portions.

The largest dimensions of the semiconductor portions are perpendicular to the largest dimension of the electrodes, the electrodes being similar.

Abstract: A semiconductor device may include a channel region formed between a source and a drain region. One or more first pockets may be formed in the channel region adjacent to junctions. The first pockets may be doped with a dopant of the first conductivity type. At least one second pocket may be formed adjacent to each of the junctions and stacked against each of the first pockets. The second pocket may be doped with a dopant of a second conductivity type such that the dopant concentration in the second pocket is less than the dopant concentration in the first pockets. The second pocket may reduce a local substrate concentration without changing the conductivity type of the channel region.
