Abstract: PURPOSE: A method for manufacturing a semiconductor device is provided to realize a thin chip assembly with a simplified assembling process. CONSTITUTION: A wafer is attached to a carrier tape and then cut to form a plurality of chips(1). Each of the chips(1) has electrodes(1a,1b) formed thereon. The chips(1) are turned over so that the electrodes(1a,1b) may face to the carrier tape. The carrier tape is then laterally extended, so a distance between the adjacent chips(1) is widened. Thereafter, each chip(1) is disposed on a lead frame(11,13) so that the electrodes(1a,1b) may get in touch with the lead frame(11,13). The lead frame(11,13) is then placed on a heat block, and a heat is applied to the heat block. The electrodes(1a,1b) of the chip(1) and the lead frame(11,13) are therefore bonded to each other. Then, the chip(1) and the lead frame(11,13) are molded, so that a chip assembly is manufactured. This method includes a direct bonding of the chip electrodes(1a,1b) to the lead frame(11,13) instead of a conventional wire bonding. Therefore, the chip assembly has a reduced thickness as a wire loop height.
