Abstract
A fan-out type semiconductor package may include a frame, an upper chip stack, a first redistribution pattern, a lower chip stack, a second redistribution pattern and a redistribution post. The frame may have a cavity. The upper chip stack may be arranged in the cavity. The first redistribution pattern may be arranged under the frame. The first redistribution pattern may be electrically connected with the upper chip stack. The lower chip stack may be arranged under the first redistribution pattern. The second redistribution pattern may be arranged under the lower chip stack. The second redistribution pattern may be electrically connected with the lower chip stack. The redistribution post may be electrically connected between the first redistribution pattern and the second redistribution pattern. Thus, the fan-out type semiconductor package may have an improved heat dissipation characteristic with a thin thickness.
