  • Publication number: 20210050275
    Abstract: A fan-out semiconductor package and packaging method thereof are disclosed. In the packaging method, a photosensitive material is used to encapsulate multiple bare chips and multiple passive devices, so multiple metal pads of each bare chip and multiple metal terminals of each passive device are exposed out of the photosensitive material by a photolithography process. The exposed metal pads and the exposed metal terminals are directly and electrically connected to a redistribution layer. In the packaging method, the bare chips and the passive devices are located on the same side of the redistribution layer and encapsulated by the photosensitive material. In addition, in the packaging method, the bare chips are not processed by a wafer bump process and does not use the thinner passive devices with high cost. Therefore, a height of the fan-out semiconductor package of the present invention is decreased and a manufacturing cost is relatively reduced.
