ELECTRONIC COMPONENT USED FOR WIRING AND METHOD FOR MANUFACTURING THE SAME

摘要

A wiring electronic component of the present invention is incorporated into an electronic device package in which a circuit element including a semiconductor chip is disposed and in which the circuit element is connected to a wiring pattern on the back face and also connected, via vertical wiring, to external electrodes located on the front face opposite the wiring pattern. The wiring electronic component is composed of an electrically conductive support portion, which serves as an electroforming mother die, and a plurality of vertical wiring portions formed through electroforming such that they are integrally connected to the support portion.
