  • Improved and more reliable plant productivity leads to improved yield

Flow Measurement & Air Bubble Detection in the Semiconductor Industry

If a cleaning solution is under- or overdosed, additional resources are required, since the cleaning process needs to be repeated. At worst, the wafers must be discarded and a huge loss in value is incurred. A precise flow measurement is therefore decisive for an efficient use of the production resources.

The presence of air bubbles in critical processes can have extensive consequences in wafer manufacturing. In photolithography the occurrence of air bubbles in photoresist may cause a defect of the wafers; air bubbles in process coolant may lead to an interruption of production processes. A timely detection of air bubbles is therefore crucial to achieve production targets.
