SEMICONDUCTOR DEVICE

摘要

In order to improve the package body cracking resistance of an LSI package at the reflow soldering and to provide both a leadframe suitable for fabricating the LSI package according to the flexible manufacturing system and an LSI using the leadframe, the adhered area between a semiconductor chip 2 and a resin is enlarged by making the external size of a die pad 3 smaller than that of the semiconductor chip to be mounted thereon. Moreover, a variety of semiconductor chips 2 having different external sizes can be mounted on the die pad 3 by cutting the leading ends of leads 5 to a suitable length in accordance with the external sizes of the semiconductor chips 2.
