Some organic electronic devices incorporate air-sensitive materials which must be processed in a pressurised glove-box. For small-molecule OLEDs (SMOLEDs), additional n- and p-type dopants and metal contacts are deposited by vacuum thermal evaporation (VTE), which currently requires the cumbersome transfer of the device into a separate vacuum system.

We have now developed a vacuum evaporation unit that can be integrated into the base of a glove-box, thus facilitating in-situ deposition.

The turbo-pumped vessel has provision for several of our valved organic evaporators, thermal or e-beam metal-contact evaporators, plus a film-thickness monitor.
