Solutions for the Semiconductor industry

A leader in innovation

For over 70 years, Conax has been the leader in the design and manufacture of compression seal fittings, temperature sensors and cable and harness assemblies for a broad range of applications across the semiconductor industry. Our expertise has helped us develop custom solutions for our customers, as well as ground-breaking technology like our exclusive EtchDefender™.

Longer TC life and lower annual spend with EtchDefender™ Technology

Our patented EtchDefender™ coating extends the life of quartz thermocouple sheaths used in epitaxial reactors up to 3X longer and reduces your annual spend by over 30%.

This leading-edge technology was tested extensively both in a laboratory setting and in a production environment at a major wafer manufacturing facility. Using TCs coated with EtchDefender™ allows a tool to run continuously and reduces maintenance cycles, consistently resulting in:

  • Increased process uptime
  • Reduced process variation, so more wafers can be produced per tool with higher
    consistency
  • Reduced labor and increased safety
  • Decreased risk of technicians igniting pyrophoric deposits as a result of reduced
    maintenance requirements
  • Decreased exposure of the chamber to oxygen, resulting in less time needed to purge the oxygen from all surfaces in SiGe applications

LeakDefender™ brand thermocouples help minimize wafer loss and maximize TC life

 LeakDefender™ brand thermocouples are used in epitaxial reactors in conjunction with the TC Sentry System™ to monitor for quartz sheath leaks in real time.

In the harsh environment of a reactor, the quartz sheath is attacked and can fail prematurely. This will cause at least one or potentially many wafers to be contaminated and scrapped, resulting in reduced tool yield.

This leakage cannot be detected right away with standard TCs, and it can lead to:

  • Operator safety concerns resulting from process gases leaking out and atmosphere leaking in
  • Wafer yield loss due to surface defects
  • Damage to the tool that can lead to premature chamber change and potential tool explosion
  • Costly unscheduled tool downtime

Conax Technologies’ LeakDefender™ brand thermocouples are used to monitor the quartz sheaths for gas leaks in real time and allow for fast shut down of the reactor. When a leak is detected in any of the TCs, the TC Sentry System™ can immediately shut down the reactor to avoid costly contamination to the chamber and minimize or totally eliminate wafer loss.

Profile and Spike Thermocouples for all the leading furnaces

Conax also offers standard or custom designed Profile and Spike Thermocouples for vertical and horizontal furnaces. Our high-precision temperature sensors are engineered to address the critical process of temperature measurement and control required for the semiconductor, photovoltaic and LED industries.

Precious Metals Reclamation

Conax Technologies manufacturers, and offers reclaim credit for, platinum/rhodium precious metals thermocouples. These are commonly called Type-S, Type-R or Type-B thermocouples. To send either thermocouples or precious metals wire to Conax for reclaim, you must first contact Conax to issue an RMA (Return Materials Authorization) number to you. When we receive your shipment, we will disassemble, remove and weigh the wire. We will then calculate the value based on the current market pricing of platinum and rhodium. This value is given to the returning company in the form of a credit to apply against current or future invoices. Please contact your Conax sales person for more details.

Conax Combo Fittings eliminate the risk of catastrophic leaks

In-process leaks under vacuum or under pressure can be costly in terms of lost time, materials and finished product. Under certain circumstances, they can also be extremely dangerous.

When customers asked us for a solution that would eliminate the risk of in-process leaks caused by sheath failures, Conax Technologies designed a Combo Fitting that has a seal for the thermocouple sheath and a secondary seal for the wires. The dual seals ensure that, if the sheath breaks or wears out, there will still be no leak into or out of the process.

For example, a solar manufacturer with a 20-day poly-crystalline ingot growth cycle experienced a leak into the chamber during a cycle, ruining the ingot and costing the customer time and money. Our Combo Fittings eliminate the risk for potential loss in the future.
