Abstract
A probe head for testing a device under test integrated on a semiconductor wafer includes a plurality of contact probes, each having a first end and a second end, and at least one first lower guide and one second lower guide at the first end. The guides are parallel to each other and have a respective plurality of first and second guide holes for slidingly housing the contact probes. At least one third lower guide is substantially parallel to the first lower guide and to the second lower guide and includes a plurality of third guide holes for slidingly housing the contact probes. The guide holes are disposed in a shifted arrangement to eliminate a scrub movement of the first ends of each contact probe of the probe head.
