Abstract
An anti-abrasion wafer probe provides vertical-only probe-tip movement while moved vertically down using the Z-axis of a 3-axis micro-positioner to establish contact with the semiconductor chip on wafer. The vertical-only movement cancels the scratching and abrasion of the chip contact plots, which, in the case of aluminum contact plots, is critical.
