METHOD OF FABRICATING CARRIER FOR WAFER LEVEL PACKAGE BY USING LEAD FRAME

According to an embodiment of the disclosure, a method of fabricating a carrier for a wafer level package (WLP) by using a lead frame, wherein the lead frame is fabricated by forming a trench and a post by performing first half etching on an upper surface of a base substrate comprising a conductive material, filling the first-half-etched surface with resin of an insulating material, removing the resin exposed to outside of the trench so that an upper surface of the trench and an upper surface of the resin are at a same level, and performing second half etching on a lower surface of the base substrate, in which a memory chip is attached to the lower surface of the base substrate.
