摘要： A semiconductor device includes: a substrate including an active region extending in a first direction; a gate electrode extending in a second direction and intersecting the active region, the gate electrode including first electrode layer(s) and a second electrode layer;, channel layers spaced apart from each other in a third direction and at least partially surrounded by the gate electrode; source/drain regions, with at least one source/drain region on each side of the gate electrode and electrically connected to the channel layers; and air gap regions in the second electrode layer between the channel layers and between a lowermost channel layer and the active region in the third direction. The first electrode layer(s) or the second electrode layer has a first thickness between adjacent ones of the channel layers in the third direction, and has a second thickness greater than the first thickness on side surfaces of the channel layers.

摘要： The present inventive concept provides semiconductor devices that may include a capacitor including a lower electrode, a dielectric layer, and an upper electrode which are sequentially stacked. An electrode-protecting layer may be provided on the capacitor. The upper electrode may include a conductive metal oxide and the electrode-protecting layer may include a sacrificial reaction layer including a metal-hydrogen compound.
