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 Current spreading Contacts Reflectors (DBRs) SiO 2 and Si 3 N 4 by PECVD without pinholes & particles, temperatures <80 C for organics processing ITO and other TCOs with customised optical and electrical performance. Choose from evaporation or low temperature sputter without GaN plasma damage p & n metal stack contact electrodes by evaporation or sputter. Deposition at high rates and without GaN damage 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 Patterning Substrate patterning for increased extraction efficiency with optimised recipes to match your exact cone angles and height requirements GaN etch by Inductively Coupled Plasma (ICP) etch with selectivity >1 and etch rates up to 200nm/min
