Semiconductor Production
With constantly evolving processes and the increasing complexity of cutting-edge fabs, semiconductor manufacturing is a relentless cycle of innovation. Because the presence of particles no bigger than a molecule can ruin a semiconductor chip – and reduce yields – vacuum valves must provide uncompromising performance in terms of particle avoidance (to avoid wafer damage) and reliability.

Lighting Production (LED, OLED)
As LED and increasingly OLED lighting has developed into a mass market, production is strongly cost-driven. High production quality and high volumes therefore also define the framework for the development of the required vacuum valve solutions. The decisive factors here are reliability, low maintenance and low operating costs.

Sub-Fab Systems
Sub-fab processes can be challenging: corrosive, abrasive, and toxic gases and/or condensation and high levels of by-products in the gas stream can all severely affect the functionality and reliability of vacuum valves. Key functions of vacuum valves include: Prevention of backflow contamination, flow rate control and pump isolation.

Thin Film Coating
A number of different processes are used for thin film coating processes, e.g. CVD, PVD, MOCVD or PECVD. All processes have in common that they take place under controlled atmospheric conditions, e.g. under argon atmosphere and under vacuum. Precise control of the vacuum and gas distribution is crucial for the efficiency of the coating process. VAT valve technologies set standards in this area.
