Abstract

PURPOSE: To obtain a low-cost semiconductor device whose outer leads are not bent or do not fall off by a method wherein the melting point of a solder used to form a solder bump is made different from that of a solder of the outer leads, the sheet thickness of the outer leads is made thicker than the sheet thickness of inner leads and protrusions or holes are formed between the outer leads and the inner leads.
CONSTITUTION: The following are provided: a semiconductor chip 1 provided with solder bumps 2 which have been formed on electrode pads as input terminals; and a lead frame 3 which is provided with inner leads 3b, of a thin sheet thickness, connected to the solder bumps 2 and with outer leads 3a that are thicker than the sheet thickness of the inner leads 3b and that are coated with a solder whose melting point is lower than that of the solder bumps 2 and in which protrusions 6 or holes 5 are formed between the inner leads 3b and the outer leads 3a. For example, the thickness of outer leads 3a is made thicker than the thickness of inner leads 3b, and protrusions 6 and holes 5 are formed so as to expand the width at the boundary between the outer leads 3a and the inner leads 3b. In addition, solder bumps 2 are formed of a material composed of 90% of Sn and 10% of Pb, and a lead frame 3 is coated with a solder composed of 60% of Sn and 40% of Pb.
