Patent ID: 11721620

Abstract:
A fan-out type semiconductor package includes: a frame including a cavity and a middle redistribution layer (RDL) structure at least partially surrounding the cavity; a semiconductor chip in the cavity; a lower RDL structure on the frame and electrically connected with the semiconductor chip and the middle RDL structure; an upper RDL structure on the frame and electrically connected with the middle RDL structure; an upper shielding pattern in the upper RDL structure to shield the semiconductor chip from electromagnetic interference (EMI); a lower shielding pattern in the lower RDL structure to shield the semiconductor chip from the EMI; and a side shielding pattern in the middle RDL structure to shield the semiconductor chip from the EMI. The upper shielding pattern and the lower shielding pattern have a thickness of no less than about 5 μm, and the side shielding pattern has a width of no less than about 5 μm.
