Webinar: Integrated Probe Card Solutions for Magnetic Testing

We invite you to join us for a webinar on Tuesday, August 25 at 1pm PDT/4pm EDT. We will discuss combining GMW’s expertise in Electromagnets & Magnetic Modeling with Celadon expertise in Probe Cards & Testing for complete integrated solutions compatible with all Probers. The fully integrated probe card is typically used for on-wafer parametric tests, modeling, characterization and wafer level reliability as well as functional tests.

Electromagnet and Probe Station Integration

An example of the collaboration between GMW and Celadon System is the GMW 5207 Projected Field Electromagnet and Probe Station Integration to optimize the performance of the combined electromagnet and probe card.

  • 5207 Electromagnet with custom Magnetic Pole Extender integrated with a Celadon Non-Ferrous VersaCore™
  • Peak Field, Continuous (35A): >1.3T
  • Peak Field, Triangle (60A): >2T
  • Single device or 4 x 4mm whole array testing
  • Celadon cards are compatible with any probe station

Additional Information

We will be discussing this integration along with other capabilities of GMW Associates and Celadon Systems on Tuesday, August 25 at 1pm PDT/4pm EDT.

Celadon’s 3000V VersaJet™ System enables on-wafer probing from room temperature to 200C

Celadon Systems, Inc., the home of “Peace of Mind Probing”, has led the industry in high temperature on-wafer probing solutions for over 20 years. When it comes to high voltage testing, the key to success is arc suppression.

Celadon VersaJet™ System including the VersaJet™ Control Unit and Heater below

Celadon’s VC20EHV™ and 45EHV™

Celadon’s High Temperature, High Voltage solution consists of a VersaJet™ Controller and Heater, 45EHV 4.5inch Adaptor and VC20EHV Probe Card.

Celadon believes there isn’t a good reason for allowing hard break downs to occur when performing high voltage testing. Celadon’s high voltage team spent almost five years developing test wafers, test methodology, test equipment, and probe cards in an effort to reduce hard break downs. Several papers were presented at various conferences reviewing test technique and system performance. Click on the highlighted link to go to the papers:

Cascade (FFI) Compass User Group, “Achieving 3000V at the Wafer Level”
SW Test, “Forget the Paschen and Embrace Turbulence”

The system is based on the popular and modular high voltage version of the VC20E VersaCore™ probe card. With pattern changes, the engineer will only need to change the VC20EHV probe card core, the rest of the set up all stays in place. This results in hundreds of hours saved in set up time.

System Overview

Here is the link to the High Voltage Product Guide

The system can support up to twelve 3000 Volt channels and 32 fully isolated low leakage channels. Celadon uses a propriety insulative material which eliminates the risk of probe beam to wafer arcing.

The VC20EHV (high voltage probe card) and 45EHV (high voltage 4.5inch adaptor) are both required in the high temperature and room temperature setups. For a room temperature set up, Celadon offers a kit that includes a regulator with a display and house air interface. This setup can extend the breakdown voltage at room temperature 50% or more as shown in the graphs below.

For high temperature testing, the VersaJet™ Controller and Heater are required for arc suppression. The air lines and electricals coming from the VersaJet™ Controller run through the VersaJet™ Heater and then are snapped into the back of the VC20EHV probe card while mounted in the 45EHV adaptor. This air stream is temperature controllable by the VersaJet™ Heater. Matching the VersaJet™ air temperature to the chuck/wafer temperature helps maintain stable DUT temperature for more accurate measurements. This connection at the VC20EHV probe card includes a safety interlock as well as air supply and thermal feedback sensors.

The directed air coming from the cap that is snapped into the back of the VC20EHV disrupts the ionization path and produces a high pressure “air bubble” at the wafer surface. This “air bubble” prevents surface arcing or die to die arcing, which can extend the break down voltage up to 50% at temperature.

Installation Example:

Celadon Cryogenic Probe Cards – Probing extremely small pads with and without a Prober at 4K

Celadon Systems, Inc., the home of “Peace of Mind Probing”, has been a critical supplier of advanced Cryogenic Probe Cards to Quantum Computing, Medical, Space and Military companies for over 20 years. These specialized cabled-out probe cards can be used down to 77K, 4K, or in some cases as cold as humanly possible.
Here are some examples:
Celadon’s Cryogenic VersaTile™

Celadon’s VersaTile™ has successfully probed at 6x9 micron test structure at 77K.
Celadon’s Cryogenic Tile-on-Card™

Celadon’s VersaTile™ and Tile-on-Card™ product families are compatible with most commercially available cryogenic probers. These cards were able to support 18 micron pitch.

Celadon has spent years researching and testing different materials to achieve stability over temperature at these extremely low temperatures. It is essential to find materials that are compatible and don’t compete with one another at temperature. If the Coefficient of Thermal Expansion (CTE) is too different between connecting parts on a probe card, cracking and breakage of part(s) can occur when going cold. When probe card materials’ CTE’s are not in equilibrium, one can expect a mess on their hands as materials can shatter at temperature.
Celadon invented the MobileProbe™ to support customers who have a cryo chamber but do not have a prober available to them.


The MobileProbe™ includes an integrated probe card which enables single die probing [post-dice]. This unit can support hundreds of probes. The MobileProbe™ enables testing at 4K. This technology is also designed to be capable of scaling to test multiple diced die, or even 4 inch and 6 inch wafers.
