Abstract:
A method for electrically testing a series of microelectronic fabrication die fabricated within a microelectronic fabrication substrate comprising:providing a microelectronic fabrication substrate having fabricated therein a series of microelectronic fabrication die; electrical testing the series of microelectronic fabrication die while employing an electrical test apparatus to thus determine from the series of microelectronic fabrication die at least one sub-series of electrically unacceptable microelectronic fabrication die; determining whether the microelectronic fabrication substrate may be reworked; and electrically retesting within the microelectronic fabrication substrate only the at least one sub-series of electrically unacceptable microelectronic fabrication die, and only if the microelectronic fabrication substrate may be reworked.
