Abstract

PURPOSE:To prevent the voltage drop in a semiconductor device by a method wherein breadth of inner lead wires to cause troubles related to voltage drop is made broader than the breadth of the other lead wires. CONSTITUTION:A cavity 10 is provided at the center of a ceramic case, and a semiconductor pellet 3 is accommodated therein. The ends of the lead wires 5 are connected to inner terminals 13. The lead wires to cause troubles related to voltage drop, namely the lead wire 5a for earth and the lead wire 5b for supply of electric power source voltage are formed broader as compared with breadth of the lead wires 5 for input/output of signal to reduce conduction resistance thereof.
