Choose a partner with staying power Choose a partner with proven LED production know how. Evatec and Corial are working together to deliver complete thin film process solutions you can rely on. With over 100 LED systems in production, our platforms are designed with the operator in mind - simple, safe substrate handling, simple operation, and easy to maintain. From low temperature processes for OLEDs to the most demanding HB LED optical stacks, our deposition and etch systems are delivered with robust processes and proven hardware for production 24/7. But delivering the equipment today is just the start: our LED support team helps with new process developments and extensions to machine capability to give our platforms the longest lifetimes in the industry.
LED Thin Film Powerhouse
LED Deposition Processes
Processes that fit together Choose from a portfolio of high rate deposition processes that fit together perfectly. From DBRs with wide angular range to pinhole free, stress free mask layers, our applications specialists are here to help you choose the best deposition technology and film designs for your production line and package design. Masks
SiO2 and Si3N4 by PECVD without pinholes & particles, temperatures <80째C for organics processing
Current spreading ITO and other TCOs with customised optical and electrical performance. Choose from evaporation or low temperature sputter without GaN plasma damage Contacts
p & n metal stack contact electrodes by evaporation or sputter. Deposition at high rates and without GaN damage
Reflectors (DBRs) Metals, metal / dielectric or DBR stacks by evaporation or sputter, customised for LED chip package design
LED Etch Processes
Hit the target every time Highly repeatable processes, wafer to wafer, run to run are the key to the highest yields on 2, 4 and even 6 inch substrates. Our sapphire substrate patterning processes (PSS) are the industry standard. For additional etch processes in your thin film stack, optimise conditions for vertical or sloped walls according to LED package design. PSS
Substrate patterning for increased extraction efficiency with optimised recipes to match your exact cone angles and height requirements
Patterning
GaN etch by Inductively Coupled Plasma (ICP) etch with selectivity >1 and etch rates up to 200nm/min
LED Production Platforms
Gold Medal performance Our production platforms already run at the world’s largest LED manufacturers. Evatec and CORIAL custom solutions include automated handling, direct wafer processing or carriers and integration of upstream or downstream process modules. Platform
