The Spark product line offers the reliability and absolute accuracy of CRDS at an affordable price. Say goodbye to cumbersome, complex, costly and labor-intensive mid-20th century technology. Gone is the need for calibration, spare parts, limited measurement ranges, and worries about drift and downtime.

The Spark is available for detection of H2O, CH4, CO, CO2, and C2H2 in many different matrices, including nitrogen, oxygen, hydrogen, and most noble gases, as well as some specialty gases, such as CO2.

Trace moisture detection as low as 3 ppb

Spark CH4

Trace-level methane detection

Spark H2O in CO2

Trace moisture detection in pure CO2

Spark CO / Spark+ CO

Trace-level carbon monoxide detection

The Piezocon® Gas Concentration Sensor has become the industry standard among semiconductor manufacturers for accurate monitoring and reproducible delivery control of chemical precursor vapors and dopant gases in CVD and MOCVD process tools.

Production-proven with over 5,000 installations worldwide, the Piezocon system provides:

• Improved process reproducibility and increased yield by tightly controlling the delivery of process gases and of precursor chemical vapors
• Lower cost-of-operation by allowing more effective use of precursor chemicals, extending the use of precursor chemical sources and reducing the duration of flow to vent
• Easier tool-to-tool matching with quantitative information directly meaningful to equipment and process engineers
• Assistance in troubleshooting malfunction of gas and vapor delivery systems by using built-in diagnostic utilities

The Extrel VeraSpec Atmospheric Pressure Ionization Mass Spectrometer (APIMS) is designed for reliable and repeatable low parts-per-trillion detection limits for contamination control in Ultra-High Purity (UHP) gases used in semiconductor and other high-tech industrial applications.

Key advantages for contamination control in the UHP Gases:

• Real-time, multi-species monitoring for critical impurities including O2, H2O, CH4, CO, CO2, NH3 and more

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.

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.

• 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
• Immediately reduces gas purchase costs by as much as 60 percent
• 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
