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

Claim 11:
12. A method of manufacturing a semiconductor package, the method comprising:
forming a first barrier conductive layer and a first seed layer sequentially on a release film attached to a carrier substrate;
forming a first mask pattern having a first mask opening on the first seed layer;
forming a first conductive pattern on the first seed layer and removing the first mask pattern, the first conductive pattern filling the first mask opening and defining a separation space;
forming a first insulating layer on the first conductive pattern and the first seed layer, the first insulating layer having a first opening;
forming a second barrier conductive layer and a second seed layer sequentially on the first conductive pattern, the first insulating layer, and the first seed layer;
forming a second mask pattern having a second mask opening on the second seed layer;
forming a second conductive pattern filling the second mask opening and removing the second mask pattern;
forming a second insulating layer on the second conductive pattern;
removing a portion of the second seed layer and a portion of the second barrier conductive layer not covered by the second conductive pattern;
removing the carrier substrate, the release film, the first barrier conductive layer, and the first seed layer;
removing the first conductive pattern, the first insulating layer having a recess area which is a space from which the first conductive pattern is removed;
removing a portion of the second barrier conductive layer, the portion of the second barrier conductive layer being not covered by the first insulating layer; and
forming a connection terminal on a portion of the second seed layer covering the second conductive pattern, the connection terminal filling a portion of the recess area.
