Challenges of Gas Detection in Semiconductor Manufacturing.

In the era of nanoscale manufacturing processes, the accuracy of gas detection directly determines product yield and production costs.

❄️

Ultra-clean environment requirements

Semiconductor manufacturing has extremely high cleanliness requirements. ISO Class 1-5 cleanrooms require strict control of gaseous molecular contamination (AMC), as even a trace amount of contamination can lead to product defects.

Process gas purity

The impurity content of high-purity gases used in processes such as CVD, etching, and ion implantation must be controlled at the ppb or even ppt level to ensure process stability and product yield.
