  • Patent number: 11536743
    Abstract: Provided is a Kelvin contact for inspection in which contacts and an insulating layer are less likely to be shifted relative to each other even after repeatedly performed Kelvin inspection. The Kelvin contact for inspection includes: a first contact having an upper contact point that comes into contact with one electrode terminal of an IC device and a lower contact point that comes into contact with an electrode pad of a substrate for inspection; and a second contact having an upper contact point that comes into contact with the one electrode terminal and the lower contact point that comes into contact with an electrode pad of the substrate for inspection. The first and second contacts are adjacently arranged to contact with the same one electrode terminal and provided with an insulating layer surrounding the entire main body area except upper and lower contact point areas including the upper and lower contact points, respectively.
