1. A semiconductor package comprising:
a circuit board;
a semiconductor chip on the circuit board;
a stiffener around the semiconductor chip, the stiffener including a first metal layer, a core layer, and a second metal layer sequentially stacked; and
an adhesive layer attaching an upper surface of the circuit board to a bottom surface of the stiffener,
wherein, in a layout view, a first length of at least one of the first metal layer, the core layer, or the second metal layer, extending in a first direction, is longer than a width of the semiconductor chip in the first direction, and
wherein, in a cross-sectional view, a thickness of the core layer is greater than a thickness of at least one of the first metal layer or the second metal layer.
