Detecting Leaks in Vacuum Systems

Leaks are the bane of vacuum systems. Leaks are one of the principal causes that inhibit the achievement of optimal base pressures. There are several approaches available to detect leaks of various sizes which do not involve expensive leak detection tools. In this course the methods to quantify leaks and a general approach to detection will be presented. In addition, specific techniques to detect leaks in rough, medium, high and ultra-high vacuum will be detailed. The use of helium-based leak detectors as well as the use of residual gas analysis for finding very small leaks will also be highlighted.

Duration: 1 Hour(s)

Vacuum Pumps for High Vacuum Applications

There is no one vacuum pump technology that can work from atmosphere down to high vacuum (pressures in the range of 10-6 Torr) and below. The achievement of low pressures in research or industrial vacuum systems requires a well-engineered combination of pumping technologies. The mechanisms to pump gases at high molecular densities are quite different from the techniques needed to move molecules once their numbers are substantially reduced. In this webinar we will discuss some of the measures required to achieve high vacuum and review the range of tools designed specifically to get to a low base pressure. Simple modeling will be introduced which will illustrate critical pressure ranges during pump down and system-specific characteristics that must be considered when determining pump down time and base pressures. The course will include details on the operating principles of rotary vane and dry scroll pumps, as well as turbomolecular, cryopumps, and oil-based diffusion pumps required to reach high vacuum.

Introduction to Residual Gas Analysis: Characterizing Partial Pressures

The precise characterization of pressure in a vacuum system requires the analysis of the residual gases that are present. Residual Gas Analysis (RGA) or partial pressure analysis provides substantially more data than can be acquired by a simple measure of total pressure. The system uses atomic mass units to distinguish atomic and molecular gases in addition to gas compounds such as CO2, finger prints, pump fluids, and other hydrocarbons. In this webinar the broad range of useful information, including trends in gas composition, outgassing rate, leak detection, and system cleanliness derived from RGA will be discussed. Principles of operation, pressure limits, sensitivity, mass ranges, spectra interpretation, detector placement, start-up and shut-down will also be discussed.

Methods to Enhance Thickness Uniformity of Thin Films by Physical Vapor Deposition

Thickness uniformity across thin films produced by physical vapor deposition requires a comprehensive understanding of a variety of techniques including thermal and e-beam evaporation as well as sputtering. Characteristics including flux density and distribution, the effects of process pressure, adatom energies, target and substrate biases, throw distance and substrate manipulation must all be considered. System-dependent features including deposition system design and source-to-substrate orientation will be discussed. Several approaches to monitor and measure thin film thickness, in-situ and post deposition, will be included with examples. In this webinar, Lesker experts will review fundamental characteristics of a variety of standard physical vapor deposition techniques and strategies to insure thickness uniformity across a range of substrate sizes.

Introduction to Solid-State Thin Film Batteries

Solid-state thin film batteries represent a breakthrough in energy storage for mobile electronic devices. In addition, thin film energy storage structures provide an opportunity to explore the theoretical limits of various cathode/electrolyte/anode combinations which may illuminate potential materials for large scale batteries for electric vehicles. The course will introduce the concept of solid-state thin film batteries, review currently available deposition techniques and highlight the benefits and limitations of this novel battery. Future directions to improve energy density through alternative materials combinations and 3-dimensional device designs will also be discussed.

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.

Vacuum Gauge Technology: An Overview of Pressure Control for Vacuum Systems

The control of pressure in vacuum systems can be critical to the achievement of process parameters necessary for certain vacuum-enabled processes. While application like thin film deposition by thermal and e-beam evaporation are enhanced by extremely low operating pressures, other techniques, like sputtering and certain chemical processes, can only be accomplished at pressures which are significantly HIGHER than the base pressure achievable by a high vacuum pumping system. The control of pressure in vacuum can be achieved by a variety of techniques. In this webinar several techniques will be described, with examples, to control operating pressure in vacuum. Both manual and automated techniques will be discussed as they apply to various applications.
