The Evatec LED process portfolio

From the cost effective deposition of the AlN buffer layers on Silicon and patterned Sapphire (PSS), to the deposition of the current spreading, reflector and contact layers or the final SiO/SiN encapsulation layers , Evatec delivers complete production solutions for LED and the new emerging micro LED technologies for substrate sizes up to 8inch.

AlN on Si or Sapphire
PVD growth of AlN buffer layers on Si or patterned Sapphire (PSS) on CLUSTERLINE® 200 II enables subsequent defect free growth of GaN multi quantum wells (MQW) for manufacture of high brightness LEDs (HBLEDs) at reduced cost per lumen.

Current spreading, Reflectors (DBRs) and Metal Contacts
We deliver proven processes for the deposition of TCOs, dielectrics and metals, tailoring our process packages for maximum light extraction according to each individual customers LED package design . Choose from the BAK Evaporator with Autoload cassette-to-cassette handling for 6 and 8 inch or the CLUSTERLINE® RAD sputter cluster platform for plasma damage free low temperature processing on GaN. These same technologies also make possible "on chip" optical layer processing too

Encapsulation
The SOLARIS is a fully automated "inline" platform offering ultra high throughput processes including SiO/SiN encapsulation processes.

The Evatec Solar Cell process portfolio

Dielectrics, metals and TCO deposition for Si Solar Cells
The SOLARIS S151 'inline" architecture drives down your manufacturing costs for deposition of backside metal contact stacks for high efficiency PERC, PERT,PERL, IBC and Heterojunction type cells. The flexible system can also be equipped for index matching layers, TCOs and ARs making it the perfect choice for process development too !

Scintillator technology for digital X ray detectors

Precision Caesium Iodide / Thallium Iodide Coatings
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.
