Vacuum Pumps for Ultra-High Vacuum Applications

The achievement of ultra-high vacuum pressures in a research or industrial system requires some extraordinary measures. Accordingly, the vacuum pumps required to reach 10-9 - 10-12 Torr are also extraordinary. In this webinar we will discuss some of the heroic measures required to achieve ultra-high vacuum and review the range of tools designed specifically to remove or trap the last few remaining gases present at these very low pressures. The course will include details on the operating principles of sputter ion pumps, sublimation pumps, and other techniques that can be employed to reach and maintain UHV pressures.

Duration: 1 Hour(s)

Introduction to Mass Flow Controllers

Mass flow controllers (MFC) are gas handling devices that allow for the precision injection of a specific gas or gases into a vacuum system. Intentionally introducing gas into a vacuum system may seem counter intuitive but is extremely useful in many applications and must be balanced with the pumping speed of the system in order to control operating pressure. There are several things to consider when specifying an MFC including degree of precision, gas type, range of flow, materials used in the construction of the MFC, and system integration. In this lecture, we will breakdown MFC’s, compare the more common technologies, and explain why MFC’s are so critical in many applications.

Introduction to Vacuum Science & System Design

This class is designed to introduce the student to basic concepts in vacuum technology and how they apply to system design and operation. Subjects covered include molecular density in vacuum, the ideal gas law, molecular flow in vacuum pressure regimes, characteristics of gas composition at various molecular densities, general principles of gas-solid interactions, vacuum pump technology, pressure sensors, leak detection and the impact of fundamental design decisions and operating practices on vacuum system performance. It is intended for people who are new to vacuum or may not have any formal training. It also provides a general review for those who have had some formal training in vacuum technology. The student should achieve a general understanding of vacuum technology as a foundation for further training in vacuum system design and thin film deposition.

Quartz Crystal Microbalance (QCM) for Thin Film Deposition Process Monitoring

Quartz Crystal Microbalances (QCM) are devices that can monitor and control the deposition rate of evaporation, sputtering, and other thin film deposition processes in real time. QCM's are highly precise mass balances that can measure increases in weight on a scale necessary to determine the rate at which atoms or molecules are adsorbed onto a substrate as a thin film grows. They can have an accuracy on the nanogram or microgram scale. This means they can resolve film thickness on the scale of tens of nanometers up to several microns. The QCM is made up of several components including an electroded quartz crystal, a temperature-controlled crystal holder, an oscillator and a controller which reads changes in oscillation, and stores process parameters. In this lecture, we will highlight each of these components, compare some of the more common options, and describe how these components work together for precise thin film deposition monitoring and control.
