Securing the Future of Semiconductor Fabrication
The semiconductor landscape in the United States is undergoing a historic expansion. With Taiwan Semiconductor (TSMC) and Intel breaking ground in Arizona, Intel’s massive investment in Columbus, Ohio, and Texas Instruments’ growth in the South, the demand for “Ultra High Pure” (UHP) infrastructure has never been higher.
Thermal Instrument Company provides the critical flow measurement technology required to support these facilities. Our Model 600-9UHP is specifically engineered to meet the stringent cleanliness and precision standards of modern chip manufacturing, ensuring that the production gases powering the digital revolution remain uncontaminated and accurately metered.
In the semiconductor industry, gases are often as expensive as the silicon they process. Gases like Silane, Argon, Nitrogen, and Ultra-High-Purity (UHP) Hydrogen are critical to the deposition and etching phases of manufacturing. For over 30 years, Thermal Instrument Company has provided the specialized mass flow solutions required to manage these costly resources. With our unique redundant sensor design and UHP-grade surface finishes, our meters are the standard for accuracy and provide years of service and Return on Investment (ROI) at the world’s leading fabrication facilities.

Trusted by Global Leaders
Our thermal mass flow technology is integrated into the most sophisticated manufacturing environments on the planet. Thermal Instrument meters are currently operational at:
- Top Manufacturers: Texas Instruments, Samsung, GlobalFoundries, and Micron.
- Industry Suppliers: TSMC, Air Liquide, and other critical infrastructure partners.
The Precision Challenge in UHP Gas Delivery
Semiconductor fabrication relies on the delivery of ultra-clean production gases. Any obstruction or roughness in the flow path can lead to particulate buildup, pressure drops, or chemical contamination—all of which are “yield killers.”
Thermal Instrument Model 600-9UHP Solution:
The Model 600-9UHP is designed to address these challenges head-on:
- Unobstructed Flow Path: Our “straight-through” design eliminates internal components that could trap particles or cause turbulence.
- Superior Surface Finish: We provide a 15 Ra surface finish or better on all wetted surfaces, ensuring a smooth, mirror-like path that prevents gas stagnation and contamination.
- Negligible Pressure Drop: Because the meters are sized exactly to your existing lines, there is virtually no loss in pressure, maintaining the integrity of sensitive delivery systems.
- The only mass flow meters in the industry featuring redundant flow and temperature sensors. If a sensor fails, the redundant sensor is there and can take over, preventing costly process interruptions and improving ROI.
- Custom Calibration: Unlike “off-the-shelf” sensors, every Thermal Instrument meter is custom-manufactured and calibrated to the customer’s specific gas mixture and environmental requirements.
Versatility Across the Fab
From micro-dosing to bulk gas delivery, the Model 600-9UHP scales to meet the specific needs of different stages of production:
| Capability | Specification / Benefit |
| Sizing Range | 1/4” OD for precise low-flow measurements up to 6” OD for tank farm monitoring. |
| Connection Options | Tube ends for orbital welding, or VCR / VCO connections for easy installation and removal. |
| Redundancy | Standard build includes backup Flow and Temperature sensors for unmatched reliability. |
| Communications | Standard 4-20mA; upgradable to HART or RS485 Modbus for Industry 4.0 integration. |
Beyond the Clean Room: Total Facility Solutions
While UHP gases are the lifeblood of the “front-end” process, Thermal Instrument mass flow meters are utilized throughout the entire facility to optimize operations:
- Compressed Air Management: Accurate monitoring of facility-wide compressed air to reduce energy waste.
- Natural Gas Sub-metering: Precise measurement for power generators and boilers critical to maintaining 24/7 production uptime.
- Cooling Systems: Monitoring water or gas flow in cooling loops to ensure expensive equipment operates within safe thermal margins.
