Modeling of Vacuum System Performance
Introduction to Vacuum System Modeling: Vacuum systems must be designed to meet certain fundamental criteria, such as base pressure, time-to-pressure, and leak tightness in order to achieve the process goals for which the systems were created. Given the complexity and cost of modern vacuum systems, predictive performance models are useful in the specification of the active (pumps, sensors) and passive (tubulations, valves) components of a vacuum system, minimizing errors, identifying technical challenges, and hopefully minimizing cost. In this webinar we will review some fundamentals of vacuum system design, including outgassing, conductance and pumping speed, review simple approaches to characterizing vacuum systems, and show some advance models which enable more wide-ranging analysis.

REGISTERMaterials for Magnetron Sputtering
This presentation is one of a three-part series about materials for physical vapor deposition. The talk will begin with an introduction to sputter technology and the general function of a sputter gun. We will then delve into the critical considerations for selecting and utilizing sputter targets for magnetron sputtering. We will emphasize the importance of properties such as maximum power density, melting point, and target composition. Additionally, the presentation will address common considerations such as target bonding, material compatibility with system components, and magnet assemblies, offering strategies for optimal material selection for thin film fabrication. Practical examples will be provided to illustrate the importance of proper material selection in achieving desired film characteristics.
