BLUGLASS DELIVERS PROCESS TRANSFER FOR SEREN PHOTONICS
BluGlass’ epitaxy (foundry) customer, Seren Photonics (Seren), achieves successful transfer of semi-polar GaN template process
BluGlass technology team facilitate the successful transfer of Seren’s GaN template process to the BluGlass MOCVD platform
The two companies will continue to work to improve the yield, uniformity and defect density
Australian technology innovator BluGlass Limited (ASX:BLG) has successfully facilitated for its customer, Seren Photonics Limited, a UK developer of semi-polar gallium nitride (GaN) products, the transfer of their GaN template process to the BluGlass MOCVD platform.
BluGlass has been working with Seren since November 2016 (BluGlass Foundry Announcement) with the objective of transferring the process from laboratory scale equipment onto a production relevant MOCVD platform.
Semi-polar gallium nitride (GaN) is an alternative GaN template for the manufacture of LEDs, that overcomes many of the problems associated with the green gap (inability to make efficient green LEDs using MOCVD) and has the potential to also address LED efficiency droop, where the LEDs become gradually less efficient at high power. Previously, semi-polar GaN was only available in small pieces, cut from a bulk GaN crystal. The Seren technology creates high quality semi-polar GaN on industry standard 2”, 4” and 6” sapphire wafers. BluGlass and Seren are working together to demonstrate commercially viable semi-polar devices including reviewing the potential to use BluGlass’ proprietary RPCVD technology to further improve the performance of green LEDs.
BluGlass will continue to work with its customer Seren, with future development now focusing on refining the manufacturing process with an emphasis on improving uniformity and yield, whilst parallel development will continue to focus on further reduction in defect density.
