    摘要: A semiconductor device includes a substrate, an active pattern disposed on the substrate and extending in a first direction, gate electrodes covering the active pattern and extending in a second direction, a gate spacer disposed on a sidewall of each of the gate electrodes, a source/drain pattern disposed between adjacent ones of the gate electrodes, an etch stop film disposed along a sidewall of the gate spacer and a profile of the source/drain pattern, an interlayer insulating film disposed between the adjacent ones of the gate electrodes with a contact trench exposing the source/drain pattern defined therein, a liner film disposed on an outer sidewall of the contact trench, and a source/drain contact disposed on the liner film and filling the contact trench, in which the source/drain contact is connected to the source/drain pattern. At least a portion of the liner film may be disposed in the source/drain pattern.

    摘要: Field effect transistors (FET) including quantum layers. A FET may include a substrate, and an oxide layer disposed over the substrate. The oxide layer may include a first section and a second section positioned adjacent the first section. The FET may also include a first quantum layer disposed over the first section of the oxide layer, and a second quantum layer disposed over the second section of the oxide layer, and a first segment of the first quantum layer. Additionally, the FET may include a drain region disposed directly over a second segment the first quantum layer. The second segment of the first quantum layer may be positioned adjacent the first segment of the first quantum layer. The FET may further include a source region disposed over the second quantum layer, and a channel region formed over the second quantum layer, between the drain region and the source region.
