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.

Duration: 1 Hour(s)

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.
