Filed:

Dec 4, 2000

Appl. No.:

09/730130

Inventors:

Bryan J. Root - Apple Valley MN

Assignee:

Celadon Systems, Inc. - Apple Valley MN

International Classification:

G01R 3102

US Classification:

324754, 324761, 324762

Abstract:

A tile used to hold one or more probes for testing a semiconductor wafer. The tile has one or more sites for inserting one or more probes to test the semiconductor wafer. Each site has one or more holes. Each hole is coupled with a slot forming an angle. A probe is inserted into the tile from a top of the tile through the hole and seated on the slot. The probe has a probe tip. The probe tip is in contact with the semiconductor wafer at one end of the slot at a bottom of the tile. The probe tip is aligned with X and Y coordinates of a bond pad on the semiconductor wafer.

Appl. No.:

10/383079

Inventors:

Bryan J. Root - Apple Valley MN, US
William A. Funk - Eagan MN, US

Assignee:

Celadon Systems, Inc. - Burnsville MN

International Classification:

G01R031/02

US Classification:

324754, 324761, 3241581

Abstract:

A method and apparatus for terminating a probe that probes a semiconductor device with a signal cable from a tester is provided to connect layers of the probe to layers of the signal cable side by side. The probe and signal cable can be a co-axial or tri-axial probe and signal cable, respectively. A center conductive probe needle of the probe is disposed side by side with and electrically connects to a center signal conductor of the signal cable. A dielectric layer of the probe is disposed side by side with and connects to a dielectric layer of the signal cable. A conductive guard layer of the probe is disposed side by side with and electrically connects to a conductive dispersion/guard layer of the signal cable, and a sleeve of the probe is disposed side by side with and connects to a sleeve of the signal cable. In a tri-axial embodiment, a second dielectric layer of the probe is disposed side by side with and connects to a second dielectric layer of the signal cable.

Appl. No.:

10/809051

Inventors:

Bryan J. Root - Apple Valley MN, US
William A. Funk - Eagan MN, US

Assignee:

Celadon Systems, Inc. - Burnsville MN

International Classification:

G01R031/02

US Classification:

324761, 324758

Abstract:

A probe needle apparatus having a conductive central core with alternating layers of dielectric and conductive materials is provided. The apparatus includes the conductive central core, a first layer of dielectric material applied to maintain electrical access to the conductive central core while providing continuous isolation of the conductive central core elsewhere, and a conductive driven guard layer applied around the first layer of dielectric material in electrical isolation from the conductive central core. The conductive driven guard layer is applied on the first layer of dielectric material with a mask on an end of the conductive central core to prevent the conductive driven guard layer from touching the conductive central core.
