Abstract
A jig used for assembling semiconductor devices has an arrangement wherein the first semiconductor integrated circuit chip, which is die-bonded and wire-bonded onto one surface of a lead frame, is fitted to the inner section of a support stage and is supported by an elastic member that is designed to be higher than the inner section, while the lead frame is supported by the outer section of the support stage. In this state, the second semiconductor integrated circuit chip is die-bonded onto the other surface of the lead frame by applying pressure by means of a bonding collet. Thus, it becomes possible to prevent cracks that may be caused in a passivation film and also to improve the reliability and the final yield of semiconductor devices.
