Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A semiconductor package comprising:
a first sub-package comprising a first semiconductor chip;
a second sub-package on the first sub-package and comprising a second semiconductor chip; and
a connection structure connecting the first sub-package to the second sub-package,
wherein the first sub-package comprises:
a frame structure comprising a core portion and a lower pad under the core portion, wherein a cavity penetrates the core portion;
wherein the first semiconductor chip is arranged in the cavity, wherein the first semiconductor chip comprises an active surface on which a bump pad is arranged and a non-active surface opposite the active surface, wherein the bump pad protrudes from the active surface of the semiconductor chip and has a polygonal column shape or a cylindrical shape;
a redistribution structure under the frame structure and the first semiconductor chip, wherein the redistribution structure is connected to the lower pad and the bump pad; and
a molding member that is on the frame structure and the first semiconductor chip, and that is in the cavity, wherein the molding member contacts a side surface of the bump pad, and wherein the molding member covers an upper surface of the core portion, a lower surface of the core portion, and a side surface of the core portion,
wherein the lower pad protrudes from the core portion, and
wherein a lower surface of the lower pad, a lower surface of the bump pad, and a lower surface of the molding member are coplanar.
