STRUTTURA DI RILEVAMENTO DELL'ALLINEAMENTO DI UNA SONDA ATTA A TESTARE CIRCUITI INTEGRATI

摘要

A sensing structure for use in testing integrated circuits on a substrate. The sensing structure includes at least two sensing regions connectable to a probe and at least one first sensing element. Each of the at least one first sensing elements is directly connected to two sensing regions such that for each sensing region a different value of an electrical parameter is measurable between the sensing region and a first reference potential so as to reliably determine a drift direction of a probe.
