PT International LLC · One-Day Training Course
Helium Leak Detection for Semiconductor Manufacturing
Build a practical understanding of vacuum integrity, helium leak testing and troubleshooting for semiconductor equipment.
Course overview
This one-day course focuses on helium leak detection in semiconductor manufacturing. It brings together the fundamentals of vacuum integrity, test-method selection, detector calibration and systematic troubleshooting so equipment teams can better understand and evaluate leak-test results.
Examples focus on process chambers, seals, fittings and maintenance situations. The course connects each topic to PTI’s semiconductor glossary for preparation and continued reference.
What attendees will learn
- Explain the purpose and limitations of helium leak testing.
- Select an appropriate approach for a given component or vacuum system.
- Recognize the importance of calibration, background and response time.
- Interpret results against specified acceptance criteria and document a repeatable test.
One-day course outline
01 · Vacuum integrity in semiconductor manufacturing
- Connect leak testing to process-chamber performance, contamination control and equipment maintenance.
- Distinguish external leaks from virtual leaks, outgassing and permeation.
- Review pressure, gas flow and the role of pumps and gauges in a test setup.
02 · Helium detection fundamentals
- Explain the role of helium as a tracer gas and how a mass-spectrometer leak detector identifies it.
- Read leak-rate units and relate measured results to specified test conditions.
- Recognize the difference between instrument sensitivity and the performance of the complete test system.
03 · Choosing a test method
- Compare vacuum spray testing with pressurized-component sniffer testing.
- Distinguish locating an individual leak from measuring total leakage.
- Discuss method selection for chambers, seals, fittings and other semiconductor equipment assemblies.
04 · Preparation and calibration
- Review test connections, system readiness and the purpose of a calibrated reference leak.
- Establish a stable background and verify the response of the configured test system.
- Plan testing around the equipment manufacturer’s instructions and the facility’s approved procedures.
05 · Leak location and troubleshooting
- Interpret signal response and recovery before moving between suspected leak locations.
- Recognize how helium background, excessive tracer gas and test technique can affect results.
- Work through troubleshooting examples involving seals, connections and chamber assemblies.
06 · Results, verification and maintenance
- Compare measurements with the applicable equipment or process acceptance criteria.
- Document the test configuration, reference leak, background, units and measured result.
- Plan repair verification and discuss how repeatable testing supports preventive maintenance.
Who should attend
Semiconductor equipment and maintenance technicians, equipment engineers, field service personnel, and process or facilities staff who work with vacuum systems and leak-test results.
