Introducing ground-breaking technology for the semiconductor industry

Conax has developed exclusive, new technology that lowers the cost of ASM® EPSILON® reactor ownership.

After eight years of development and testing, Conax introduces EtchDefender™ coating that protects quartz thermocouple (TC) sheaths during the epitaxial process in ASM® EPSILON® reactors—extending TC life up to 3 times longer.
The epitaxial process takes place at one of the highest temperatures of any in the manufacturing of integrated circuits. Because the ASM® EPSILON® single-wafer epitaxial tool uniquely utilizes thermocouples that are installed inside the reactor chamber for process control, the thermocouples are exposed to two temperature cycles that can range from 600°C to 1200°C for each wafer processed.

The second temperature cycle is the etch process, which is used to clean the chamber and all the internal components with hydrochloric acid at extremely high temperatures. As thermocouples are subjected to these cycles and corrosive hydrochloric acid etches, the quartz sheath is attacked and ultimately fails, requiring a maintenance cycle to replace them.
“Our goal was to develop a solution that protects the quartz sheath during the etch process and slows devitrification to extend its life and eliminate maintenance cycles needed solely to replace thermocouples,” said Conax Technologies Business Unit Manager, Mike Ferraro. “With EtchDefender™, we hit on the right formula.”


Testing in the laboratory and at a major Fab has shown that:

  • EtchDefender™ coating is well adhered and will not flake from the quartz substrate, which causes particle contamination to the wafer.
  • The coating does not decompose, out-gas or sublimate under vacuum at high temperature.
  • EtchDefender™ greatly slows the devitrification process typical of quartz sheaths used in the EPSILON® by retarding the loss of oxygen from the SiO₂ quartz sheath at temperatures more than 900°C.
  • The coating greatly retards the erosion process caused by hot corrosive gases flowing at high concentrations and velocities. This is most relevant in extending the life of the Center Thermocouple.


“Using TCs coated with EtchDefender™ allows a tool to run continuously and reduces maintenance cycles,” said Ferraro. “This results in increased process uptime and reduced process variation for our customers, so more wafers can be produced per tool with higher consistency.”

Silicon wafer shipments on the rise

In a quarterly analysis of the silicon wafer industry by SEMI® Silicon Manufacturers Group (SMG), worldwide silicon wafer shipments increased during this year’s third quarter. SMG is an independent special interest group of SEMI members whose efforts focus on issues related to the silicon industry. Specifically, SMG focuses on the development of market information and statistics about the silicon industry and the semiconductor market.

Silicon wafers are the building material for most electronics, like computers, cell phones and tablets. Shaped like round disks, silicon wafers can be from one inch to 12 inches in diameter.

What it means for Conax and the consumer

Approximately 20% of all wafers produced begin with the addition of an epitaxial layer. To meet the higher demand, Conax is increasing production capacity of its epitaxial wafer thermocouples. We’re also manufacturing a new version of the thermocouples for the ASM® EPSILON® tool, which will significantly increase thermocouple life and lower the cost for our customers.
