A semiconductor package includes a frame having first and second through-portions, first and second semiconductor chips, respectively in the first and second through-portions, each having a first surface, on which a connection pad is disposed, a first encapsulant covering at least a portion of the first and second semiconductor chips, a first connection member on the first and second semiconductor chips including a first redistribution layer electrically connected to the connection pads of the first and second semiconductor chips and a heat dissipation pattern layer, at least one passive component above the first semiconductor chip on the first connection member, and at least one heat dissipation structure above the second semiconductor chip on the first connection member and connected to the heat dissipation pattern layer.
