Abstract

A resin encapsulated semiconductor package, which uses leads (lead frame), and enhances heat conducting properties and prevents breaking of lengths of bonding wire, reduction in service life of solder joints and crack of a resin while ensuring reliability on strength. A lead material uses a material containing as a main constituent material a composite alloy of Cu2O and Cu, which has a thermal conductivity as high as that of copper alloys having been conventionally used, and which is sintered to have a small linear expansion coefficient as compared with such copper alloys.
