A chuck that includes an upper surface for supporting a device under test and a conductive element that extends through the chuck to the upper surface of the chuck. The conductive element is electrically isolated from the upper surface of the chuck, and makes electrical contact with any device under test supported by the chuck.
The invention claimed is: 1. A probe station for probing a device under test having a probing surface, said probe station comprising: (a) a chuck having an upper surface suitable to support said device under test, and at least one probe suitable to probe said device under test while said probing su
The invention claimed is: 1. A probe station for probing a device under test having a probing surface, said probe station comprising: (a) a chuck having an upper surface suitable to support said device under test, and at least one probe suitable to probe said device under test while said probing surface is facing away from said upper surface; (b) a conductive element electrically isolated from said upper surface of said chuck and extending through said chuck to said upper surface of said chuck; and (c) said conductive element positioned so as to electrically contact said device under test when said device under test is being probed by said at least one probe and while said probing surface is facing away from said upper surface; (d) said conductive element is electrically interconnected to the edge of said chuck. 2. The chuck of claim 1 wherein said device under test is interconnected to a force connection. 3. The chuck of claim 1 wherein a sense connection is interconnected to the backside of said device under test. 4. The chuck of claim 1 wherein said conductive element included a moveable contact at its terminal end. 5. The chuck of claim 1 wherein said conductive element includes a portion ending above the upper surface of said chuck. 6. The chuck of claim 5 wherein said portion ends above the upper surface of said chuck when said device under test is not supported by said chuck.
