ABSTRACT:
A prefabricated lead frame to bond a chip and a substrate, and a bonding method using the prefabricated lead frame. The prefabricated lead frame includes an inner ring, an outer ring, and a plurality of wires, wherein inner ends and outer ends of the wires are respectively connected to the inner ring and the outer ring, and the prefabricated lead frame has a wire shape corresponding to a chip and a substrate to be bonded. The prefabricated lead frame may be manufactured in batch production to increase the manufacturing efficiency of semiconductor devices, and the prefabricated lead frame may be used instead of a general wire bonding process.
