Abstract
Within a method for electrical test testing a series of microelectronic fabrication die fabricated within a microelectronic frabrication substrate, there is first electrical probe tested the series of microelectronic fabrication die to determine at least one sub-series of electrically acceptable microelectronic fabrication die. Each electrically acceptable microelectronic fabrication die within the at least one sub-series of electrically acceptable microelectronic fabrication die is then electrical probe retested, but electrically unacceptable microelectronic fabrication die within corresponding sub-series of electrically unacceptable microelectronic fabrication die are not.
