[Effects of the Invention] As described above, according to the present invention, the distance between the outer periphery of the chip and the outer shape of the resin molding body can be reduced, the outer shape can be made smaller, and even if the resin molding body has the same outer shape, For example, a larger chip can be accommodated than in the past, and the strength of the external leads is maintained as in the case of the conventional wire bond method. In addition, the electrode position on the chip is not restricted to the periphery as in the past, but can be placed in the center. In this case, the wiring length to the electrode within the chip can be shortened, resulting in high speed and improved noise resistance. Ru. Furthermore, the process of die bonding the chip to the lead frame is omitted, and the connections between each electrode of the chip and each internal lead are processed at once, thereby shortening the manufacturing process. Furthermore, there is no die pad on the lead frame, and the resin sealing body has a chip housing structure without a die pad, improving crack resistance due to thermal stress.
