    Abstract: A semiconductor device includes a substrate including an active pattern, a channel pattern including a first semiconductor pattern and a second semiconductor pattern, a source/drain pattern connected to the first and second semiconductor patterns, and a gate electrode including an electrode between the first and second semiconductor patterns, and an insulating layer between the first and second semiconductor patterns and the electrode. The insulating layer includes a dielectric layer enclosing the electrode and a spacer on the dielectric layer. The spacer includes a horizontal portion between the dielectric layer and the second semiconductor pattern, a vertical portion between the dielectric layer and the source/drain pattern, and a corner portion connecting the horizontal portion to the vertical portion. A first thickness of the horizontal portion is smaller than a second thickness of the vertical portion, and the second thickness is smaller than a third thickness of the corner portion.
