Semiconductor Gas Analysis and Moisture Control
Maintain control of gas purity and process stability in semiconductor manufacturing
When your process depends on ultra-high purity
In semiconductor manufacturing, process stability depends on how well you control gas purity. Even trace levels of moisture or contaminants can affect product quality, disrupt critical steps, and lead to yield loss.
You are often working with ultra-clean gases and tightly controlled environments, where small deviations can have a disproportionate impact on performance and consistency.
For Semiconductor applications these are some of the parametres we can help you measure, monitor and analyse:
- H₂O (trace moisture / dew point)
- O₂ (trace oxygen)
- N₂, H₂, Ar (high-purity gases)
- CO, CO₂
- Hydrocarbons at trace levels
- Other impurities in specialty gases
Small deviations – significant consequences
Compared to many other industries, semiconductor processes operate at a different level of sensitivity. Measurement is not just about monitoring – it is about detecting changes early enough to act before they affect your process.
You may experience:
- Trace moisture at ppb levels influencing product quality
- Risk of contamination in high-purity gas systems
- Variations in gas composition affecting process stability
- Limited tolerance for drift or delayed measurements
- High cost of deviations, scrap, and downtime
Understanding what happens in your gas system
To maintain stable conditions, you need reliable insight into what is happening in your gas streams – in real time and at the required level of sensitivity.
Trace moisture measurement at ppb levels
Monitoring moisture at very low concentrations allows you to detect contamination early and maintain control of ultra-dry gas systems.
Dew point monitoring in process and supply lines
By measuring dew point directly in your gas system, you can identify changes in moisture levels and reduce the risk of condensation or process disturbances.
Multi-component gas analysis
Understanding the full gas composition helps you identify impurities and variations that may influence your process or final product.
Reference measurements for validation
High-accuracy reference instruments allow you to verify and validate your measurements, which is particularly important in controlled and regulated environments.
A structured approach to measurement and integration
Working with semiconductor processes often requires more than standalone instruments. Measurement needs to be integrated into your process in a way that supports stability over time.
We support you with:
- Selection of measurement principles suited to ultra-low detection levels
- Integration of analyzers into existing gas systems
- Consideration of sampling, response time, and system design
- Long-term stability and maintainability of measurement solutions
What this means in practice
When you have reliable measurement data, you are better equipped to maintain stable operating conditions and make informed decisions.
In practice, this means:
- More stable and repeatable process conditions
- Reduced risk of contamination and off-spec production
- Better protection of sensitive equipment
- Fewer unexpected interruptions in production
- A stronger basis for process control and optimization
