Abstract

See full text

Provided are a method for fabricating a semiconductor package and a semiconductor package using the same, which can simplify a fabricating process of the semiconductor package by forming a lead frame on which a semiconductor die can be mounted without a separate grinding process, and can improve product reliability by preventing warpage from occurring during a grinding process. In one embodiment, the method for fabricating a semiconductor package includes forming a frame on a carrier, forming a first pattern layer on the frame, first encapsulating the frame and the first pattern layer using a first encapsulant, forming conductive vias electrically connected to the first pattern layer while passing through the first encapsulant, forming a second pattern layer electrically connected to the conductive vias on the first encapsulant, forming a first solder mask formed on the first encapsulant and exposing a portion of the second pattern layer to the outside, removing the frame by an etching process and etching a portion of the first pattern layer, and attaching a semiconductor die to the first pattern layer.
