Abstract: A semiconductor device includes; a gate structure intersecting an active region, and a plurality of channel layers, extending on the substrate in a second direction, and surrounding the plurality of channel layers; a source/drain region contacting the plurality of channel layers on at least one side of the gate structure and including a first semiconductor material with first impurities having a first conductivity type; and a lower structure in contact with the active region and below the source/drain region. The lower structure includes a first layer disposed on the active region and including an insulating material; a second layer disposed on the first layer and including a second semiconductor material; with an air gap defined by the first layer and the second layer, wherein the second semiconductor material of the second layer has no conductivity type or has a second conductivity type different from the first conductivity type.
