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

Claim 11:
12. A method for manufacturing a semiconductor package, comprising:
mounting, on a substrate, a first semiconductor chip having a through electrode;
forming a second semiconductor chip;
disposing the second semiconductor chip on the first semiconductor chip such that a drip pad of the second semiconductor chip is in contact with the through electrode of the first semiconductor chip; and
forming a molding layer on the substrate,
wherein the forming of the second semiconductor chip includes:
forming a lower protective layer of a first insulation material on a bottom surface of a base layer having an integrated circuit;
forming the chip pad connected to the base layer through the lower protective layer; and
forming an additional protective layer of a second insulation material on the lower protective layer,

wherein a Young's modulus of the additional protective layer is about 0.1 times to about 0.5 times as great as a Young's modulus of the lower protective layer, and
wherein, after disposing the second semiconductor chip on the first semiconductor chip, the through electrode and the chip pad are coupled to each other.
