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

Claim 0:
1. A method of manufacturing a semiconductor package, the method comprising:
forming a first insulating layer;
forming a lower seed layer on the first insulating layer;
forming a lower bump pad on the lower seed layer, the lower bump pad having a first surface in physical contact with the lower seed layer;
forming at least one redistribution pattern electrically connected to the lower bump pad and at least one insulating layer on the first insulating layer;
disposing a semiconductor chip on the at least one redistribution pattern;
forming a pad opening of the first insulating layer by removing a portion of the first insulating layer, wherein a first part of the lower seed layer is exposed through the pad opening of the first insulating layer; and
removing the first part of the lower seed layer exposed through the pad opening of the first insulating layer to expose a portion of the first surface of the lower bump pad.
