Abstract

PURPOSE: To enhance both the conductivity of heat and electricity and the heat- resistance performance as well as to improve the working property by using the copper alloy composed by adding 0.005W0.1% zirconium to the copper for the lead material used to the semiconductor apparatus.
CONSTITUTION: The copper alloy composed by adding 0.005W0.1% zirconium to the copper is used as the lead material for the semiconductor apparatus. As a result, a high conductivity and high heat-resistance can be obtained along with the enhanced working property for the plating and bending processes. At the same time, such processes are carried out by the conventional alloy processors as the casting, processing, annealing and others. Also, the electric conductivity approximate to the pure degree can be obtained by selecting the quantity of the zirconium. Thus, a lead material excellent in every characteristics compared with other alloys.
