HVA: 81000 Series Aluminum Gate Valves

The 81000 Series Aluminum Gate Valves are designed for high vacuum applications specifically when pressure ranges approximate 1 x 10-7 mbar and bakeout temperatures do not exceed 150°C. These valves are designed for system integrators, designers and OEM’s within the Semiconductor, Solar, LED/FPD, Coating and BioPharm industries due to their robust design and low cost. They feature precision machined high strength aluminum bodies from solid 6061-T6 billet, dual quad ring long life shaft seals and high performance PEEK components.

Hiden Analytical: Hiden Analytical Ltd Introduces Environmentally-Focused QGA 2.0 Gas Analyser

Hiden Analytical Ltd is excited to announce its latest innovation in gas analysis technology – the QGA 2.0, which sets a new standard in environmental sustainability. The QGA 2.0 is not just a leap forward in performance but also a champion of eco-friendly practices. This advanced system is designed with sustainability at its core, using sustainable materials and being fully recyclable at the end of its life. The QGA 2.0 showcases a significant reduction in weight and size, leading to more efficient shipping and a smaller carbon footprint.

American Elements: Three-dimensional nanoscale metal, metal oxide, and semiconductor frameworks through DNA-programmable assembly and templating

Controlling the three-dimensional (3D) nanoarchitecture of inorganic materials is imperative for enabling their novel mechanical, optical, and electronic properties. Here, by exploiting DNA-programmable assembly, we establish a general approach for realizing designed 3D ordered inorganic frameworks. Through inorganic templating of DNA frameworks by liquid- and vapor-phase infiltrations, we demonstrate successful nanofabrication of diverse classes of inorganic frameworks from metal, metal oxide and semiconductor materials, as well as their combinations, including zinc, aluminum, copper, molybdenum, tungsten, indium, tin, and platinum, and composites such as aluminum-doped zinc oxide, indium tin oxide, and platinum/aluminum-doped zinc oxide. The open 3D frameworks have features on the order of nanometers with architecture prescribed by the DNA frames and self-assembled lattice. Structural and spectroscopic studies reveal the composition and organization of diverse inorganic frameworks, as well as the optoelectronic properties of selected materials. The work paves the road toward establishing a 3D nanoscale lithography.

Pfeiffer Vacuum: Pfeiffer Vacuum introduces new HiCube® Neo turbo pumping station

With pumping speeds ranging from 80 to 800 l/s, the HiCube Neo vacuum pumping station is ideal for demanding high vacuum and ultra-high vacuum applications. The HiCube Neo can be prepared for wide-ranging applications with an array of different backing pumps such as diaphragm, rotary vane, scroll and multi-stage Roots pumps. This makes the new turbo pumping station perfect for applications in industry and research & development. Typical uses range from analyzing gases and calibrating vacuum gauges to pumping down cryostats and use in vacuum furnaces. The versatile HiCube Neo adapts to requirements – from a compact desktop solution to a standalone unit.

Vacuum Technology Primer

Since 2000 Vacuum Technology & Coating Magazine has been the industry's leading source for the latest articles, news, and product and service information. Below we describe some of the terms that you will find in a typical issue of VT&C.

Vacuum Coating (Vacuum Deposition and Thin Film Deposition) is the process of depositing a film or other material atom by atom or molecule by molecule onto a surface in a low pressure environment or vacuum.

Physical Vapor Deposition or PVD refers to vacuum deposition methods which involve the material (which is being deposited) going from a condensed phase to a vapor phase and then to a thin film condensed phase. Sputtering and evaporation are common PVD processes.

Sputtering refers to a type of process used to deposit thin films and employs a plasma to bombard and eject atoms from a target source.

Evaporation refers to the heated source material being evaporated in a vacuum. Vacuum allows vapor particles to travel directly to the target object, where they condense back to a solid state. (called a Deposition Source) refers to a type of process used to deposit thin films and employs a plasma to bombard and eject atoms from the target source (called a Deposition Source).

Vacuum Hardware refers to the types of hardware and components that are used in the vacuum process. There are many types of hardware used in this process, some examples are flanges, fittings, seals, valves, and chambers.

Thin Film Metrology involves determining the optimal thickness, composition and/or condition of a coating through various techniques and mathematical calculations.

Gas Analytical Systems are used in the analysis of residual gases within a low pressure environment or vacuum.

Vacuum Pumps are devices that remove gas atoms and molecules for the purpose of leaving behind a partial vacuum. Some examples of types of vacuum pumps are rotary vane pumps, diaphragm pumps, and scroll pumps.

Every issue of VT&C includes a product showcase focused on a specific topic relevant to Vacuum Processing, please see our editorial calendar which lists the topic for each issue.
