Patent ID: 7804313

Claim:
A semiconductor IC array comprising: semiconductor ICs arranged in an array, each being to be tested with a plurality of probe needles: at least one group of metal marks electrically isolated from the probe needles and arranged in a pattern to cooperate with at least one of the probe needles to detect appropriate displacement in probing for the semiconductor ICs, wherein the metal marks are electrically isolated from one another and each have a probed surface smaller than a tip surface of a probe needle; and an electrically insulating film which covers the at least one group of metal marks to electrically isolate the at least one group of metal marks from the probe needles and holds capacitances between the metal marks and the at least one of the probe needles placed on the film, wherein the capacitances are a function of relative distances between the metal marks and the at least one of the probe needles placed on the film.
