摘要： Copper alloy lead materials used in the fabrication of semiconductor devices such as ICs and LSIs are required to have a tensile strength of 40 kgf/mm.sup.2 or more, an elongation of 4% or more, an electrical conductivity of 50% IACS or more, and a softening point of 400.degree. C. or higher.The copper alloy lead material of the present invention exhibits even higher degrees of tensile strength and elongation and yet satisfy the values of electrical conductivity and softening point that are required for Cu alloy lead materials to be used with ordinary semiconductor devices. Therefore, the Cu alloy lead material of the present invention is applicable not only to ordinary semiconductor devices but also to those with higher packing densities while displaying equally superior performance.
