Evatec delivers complete thin film solutions for high precision (HP) optical layers using evaporation and sputter combined with Advanced Process Control ( APC) technologies.

Our production platforms enable the deposition of filters, ARs, DBRs and other high performance coatings including Hard and Antismudge coatings. Evatec processes enhance the performance of the sensors, cameras and the touch screens of our smart devices, the combiners in our Head Up Displays (HUD) in our cars and provide the right lighting conditions in our operating theatres.

Evatec process capabilities support other applications too, including the manufacture of CsI /TlI based scintillators for high performance digital X ray detectors in medical applications. Evaporation solutions on Evatec's large area BAK1401 and BAV2000 box coaters with custom source technologies deliver precise stoichiometry and columnar layer structures in the films required in scintillator manufacture for digital x ray detectors.

Advanced Process Control (APC) for High Precision Optical Layers

Evatec production platforms integrate a range of closed loop process control technologies for improved precision and yield:

  • Broadband Optical Monitoring for direct substrate measurement with In-situ reoptimisation for real time recipe adjustment during evaporation or sputter deposition
  • Plasma Emission Monitoring for perfect stoichiometry control and higher throughputs in sputter
  • Optical Pyrometry in evaporation and sputter processes for enhanced temperature control in IR technologies
