VARIABLE SPACING FOUR-POINT PROBE PIN DEVICE AND METHOD

摘要

A continuous variable spacing probe pin device, including first and second probe pins. The first and second probe pins are configured to measure a property of a conductive layer. In a first configuration, the first and second probe pins include respective first portions arranged to contact the conductive layer to measure the property. In a second configuration, the first and second probe pins include respective second portions arranged to contact the conductive layer to measure the property. A first area for each respective first portion is different from a second area for each respective second portion.
