Patent ID: 8502318

Claim:
A microelectronic device comprising, on a substrate, at least one element comprising: one or more first transistors including, in a direction forming a non-zero angle with the main plane of the substrate, a number n of parallel channels in a form of a plurality of bars parallel to each other and to the substrate, said bars being formed in a first stack comprising a first number of semiconductor layers and being aligned in a direction forming a non-zero angle with the main plane of the substrate; and one or more second transistors including, in a direction forming a non-zero angle with the main plane of the substrate, a number m of parallel channels such that n>m in a form of a plurality of bars parallel to each other and to the substrate, said bars being formed in a second stack comprising a second number of semiconductor layers different from said first number of semi-conductor layers and being aligned in a direction forming a non-zero angle with the main plane of the substrate.
