Abstract
An electronic device includes a transistor. The transistor includes: a substrate including an active region that extends in a first direction; a gate structure disposed in the substrate and crossing the active region in a second direction that crosses the first direction; recesses disposed in the active region on two sides of the gate structure in the first direction, a center of a bottom surface of a first recess being more depressed in a third direction than two edges of the bottom surface along the first direction, the third direction being perpendicular to the first and second directions; an insulating layer disposed in the first recess; and a junction layer disposed over the insulating layer in the first recess in the third direction, a top surface of the insulating layer being below the two edges of the bottom surface and having a smaller curvature than the bottom surface.
