PURPOSE:To uniformly operate transistor chips and prevent the breakage of the transistor chips by providing wires having different resistances connecting between the transistor chip and a MOS-C, the MOS-C and an internal lead, and the transistor chip and the internal lead, respectively. CONSTITUTION:Input to a transistor chip 1 is accomplished from an inner lead 2 through a large diameter wire 6 in wires 4, a MOS-C3 and the wire 6. Output to the internal lead 2 is accomplished from the transistor chip 1 through the large diameter wire 6 in the wires 4. At that time since the resistance value of central wire 4 is higher than that of the thick wire 6 on the outer side, current does not concentrate on a transistor chip 1 in the center. The material of wire may be changed to change the resistance values. |
