Abstract

This discloses a probe structure which does not rely on cantilevered wire and which has improved and controlled contact pressure between the probe tip contacts and the I/O pads on a semiconductor chip and which comprises a plurality of conductive contact electrodes, electrically coupled to respective leads, formed on a film stretched across a respective plurality of through holes established in a substrate. The through holes and the contact electrodes are aligned with one another and both positionally match selected I/O pads existing on a semiconductor chip to be probed. Also disclosed is a probe utilizing means connected to each one of the holes to control the pressure in the holes and between the probes and any contact on a device in contact with the probe.
