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; electrically testing within the microelectronic fabrication substrate the series of microelectronic fabrication die while employing an electrical probe apparatus which sequentially repositions an electrical probe head which accommodates at least one microelectronic fabrication die within the series of microelectronic fabrication die when electrically testing each of the microelectronic fabrication die within the series of microelectronic fabrication die to thus determine from the series of microelectronic fabrication die at least one sub-series of electrically acceptable microelectronic fabrication die; and electrically retesting only the at least one sub-series of electrically acceptable microelectronic fabrication die.
