PURPOSE:To protect a bonding wire and a LSI chip by interposing a fuse for protection against overcurrents to an electric circuit between a terminal for a power supply or grounding and the LSI chip and annexing the fuse to the outer surface of a case proper. CONSTITUTION:A LSI chip 2 is mounted to a case proper 1, and a plurality of terminals containing terminals 3, 4 for a power supply or grounding are fitted. Electric circuits 5a, 5b tying the chip 2 and the power supply terminal 3 or the grounding terminal 4 are set up into the main body 1. Fusesfor protection against overcurrents are interposed to one parts of the electric circuits 5a, 5b, and fuses 7a, 7b are annexed to one parts of the outer surface of the main body 1. When overcurrents flow through the fuses 7a, 7b in the constitution, the fuses 7a, 7b are fusion-cut by the currents, and the electric circuits 5a, 5b are opened, thus protecting bonding wires 6a, 6b and the chip 2. |
