The Complete Solution for Precision Point-of-Use Gas Mixing

The Apex Gas Mixing System, powered by Veeco’s production-proven Piezocon® Gas Concentration Sensor, allows manufacturers to reduce production costs by purchasing lower-cost, higher-concentration gases, then diluting at the point of use to immediately reduce gas purchase costs by as much as 60 percent. By using Piezocon to measure and control the mixture in real time, manufacturers eliminate the problems associated with constant flow mixers requiring wasted materials and constant scrubbing, furthering the already substantial cost savings. The stable output and precise control of gas concentration allows Apex to drive higher process tool up-time, eliminating the need to re-qualify after every gas cylinder change, reducing—and in some cases fully eliminating—system down-time due to routine cylinder changes. Apex drives real-time control, high precision and reproducibility and lowers cost of ownership for semiconductor manufacturers.

• Immediately reduces gas purchase costs by as much as 60 percent
• Optimized for applications requiring low-concentration, high-precision and cost-sensitive gas mixtures
• Improves repeatability by 10x or more when compared to individual gas cylinders
• Increases system up-time by eliminating excursions and re-qualifications, and reducing test time
• Seamlessly integrates with existing installed base for a wide range of applications including solar, semiconductor and more
• The only gas mixing system that uses Veeco’s Piezocon Gas Concentration Sensor for ppm-level control

For real-time control, high precision and repeatability, and lower cost of ownership, count on the Apex Gas Mixing System from Veeco.

WetSpec200: Wet Process Concentration Analyzer

Multi Channel Concentration Analyzer

CI-SEMI’s in-line, multi-channel wet process analysis system, WetSpec 200 enables non-contact real-time monitoring and closed-loop control of chemical composition in wet process applications.

The WetSpec200 is ideal for monitoring, cleaning and etching chemistries. Based on CI-SEMI’s novel chemo-metric methodology, the WetSpec200 measures the absorption spectrum in the near infrared (NIR) fast and accurately without labor and waste involved.

The system’s versatile SW models enable soft-switch between different chemistries. With the capability to monitor up to eight flow cells in parallel, the WetSpec200 provides an efficient, low cost per channel process monitoring.

When integrated into a control system, the WetSpec200 enables tighter process control and identifies process excursions before they affect yield.

Dissolved Ozone Destruct Unit SOD to Integrate / Upgrade into a Wet Bench or Spray Tool

Ozone is widely used in the Semiconductor Industry, so draining of water and acids containing Ozone is a common problem. As Ozone is too dangerous, Ozone has to be destroyed before it leaves the equipment into the drain system of a FAB. This UV based Ozone destruct unit can be integrated into the wet equipment. Ozone can be effectively removed down to harmless levels  below 1ppm. This means the drain will last longer, no Ozone outgasses from the solution, and therefore no Ozone is distributed on the FAB via the drain.
