Abstract

According to the present invention, a semiconductor chip is mounted on a zigzag in-line type package (ZIP) partially using a tabless lead frame and bonding pads are arranged on the chip so that the chip can be applied also to other different types of packages. As different types of packages there are a small out-line J-bent type package (SOJ) for which there is used a lead frame with tab and a dual in-line type package (DIP) for which there is used a tabless lead frame. Further, a plurality of bonding pad pairs are provided among the bonding pads on the chip each pad of such bonding pad pairs having the same function as the other pad associated therewith thereby duplicating a common function in different bonding pads on the semiconductor chip so as to readily facilitate, or make compatible, the semiconductor chip to a variety of or different types of packages.
