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

Claim 19:
20. A method of manufacturing a semiconductor package, the method comprising:
preparing a semiconductor chip having an active surface, and comprising contact pads arranged on the active surface, and a first insulating film disposed on the active surface and exposing the contact pads, and a second insulating film disposed on the first insulating film and comprising a first opening exposing connection regions of the contact pads;
preparing a frame having first and second surfaces opposing each other and comprising a cavity penetrating through the first and second surfaces;
attaching the second surface of the frame to an adhesive film;
disposing the semiconductor chip in the cavity of the frame such that the active surface is attached to the adhesive film;
encapsulating the semiconductor chip in the cavity of the frame using an encapsulant;
removing the adhesive film from the semiconductor chip and the frame;
forming a conductive crack preventing layer on the connection regions and extending onto a portion of the second insulating film around the first opening;
forming a first insulating layer on the active surface of the semiconductor chip and the second surface of the frame to cover the conductive crack preventing layer;
forming a second opening in the first insulating layer, the second opening exposing a portion of the conductive crack preventing layer on the connection regions; and
forming a first redistribution layer electrically connected to the connection regions through the second opening and extending onto the first insulating layer.
