Thin Film Processes

Thin film processes are a key technology for a growing number of novel high tech products, like organic electronics (including organic LEDs and organic solar cells), display technology, sensor technology or microelectronics.

Thin film technology creates a lot of challenges to researchers and developers. They have to be produced at an extreme precision level, down to a few molecular layers. Creating such thin layers, however, also means that they need to be structured in the same precise manner. Lasers are well suited to meet this challenge. They can ablate very thin films without affecting the substrate underneath. Lasers can precisely modify film characteristics or generate micro structures. Due to its flexibility, a laser can process thin films on rigid substrates such as wafers or glasses, but also those on flexible substrates in roll-to-roll processes.

LUNOVU laser systems for thin film processes are exactly matched to the individual materials to be processed. This is where we leverage the sound process and application know-how of the LUNOVU specialists. A close co-operation with material scientists, process developers and end users makes sure that LUNOVU is always technologically ahead. Even most complex thin film laser processes can reliably be transferred into industrial production.
