Abstract: A fan-out semiconductor package includes a frame comprising wiring layers, and a dummy layer, and having a recessed portion on a bottom surface on which a stopper layer is disposed; a semiconductor chip disposed in the recessed portion such that an inactive surface opposes the stopper layer; a first interconnect structure disposed on the connection pad; a second interconnect structure disposed on the outermost wiring layer; a dummy structure disposed on the dummy layer; an encapsulant encapsulating at least portions of the frame, the semiconductor chip, the first interconnect structure, the second interconnect structure, and the dummy structure, and filling at least a portion of the recessed portion; and a connection member disposed on the frame and an active surface of the semiconductor chip, and comprising a redistribution layer electrically connected to first and second metal bumps. The dummy structure has sloped side surfaces.
