Abstract
A method of manufacturing a stacked package includes a first process of stacking a semiconductor chip on an upper surface of a PCB having a wiring pattern and a via-hole pad, a second process of forming a photoresist (PR) layer on the upper surface of the PCB having the semiconductor chip and the via-hole pad, a third process of removing the photoresist layer of a remaining region except for an upper portion of the via-hole pad so that a photoresist layer of a via-hole region remains only at the upper portion of the via-hole pad, a fourth process of forming a molding layer by molding the upper surface of the PCB having the semiconductor chip to expose an upper surface of the photoresist layer of the via-hole region, and a fifth process of removing the photoresist layer of the via-hole region to form a via-hole on the via-hole pad.
