Abstract
A method is provided and includes forming a first conductive pattern; forming a photosensitive layer on the first conductive pattern, the photosensitive layer having a first through hole exposing a portion of the first conductive pattern; forming a first via in the first through hole; removing the photosensitive layer; forming a dielectric layer encapsulating the first conductive pattern and the first via, the dielectric layer exposing a top surface of the first via; forming a second conductive pattern on the top surface of the first via, forming a dielectric layer covering the second conductive pattern; etching the dielectric layer to form a second through hole that exposes a portion of the second conductive pattern; forming a second via filling the second through hole and an under bump pad on the second via; and mounting a semiconductor chip on the under bump pad using a connection terminal.
