Next generation material for microLEDs; the relevance of cubic-GaN

Commercially available visible wavelength LEDs originated in the 1960s and yet sixty years later, there is still a huge amount of research and investment in this sector. Technological and environmental advances necessitate device miniaturisation, higher light output, reduced power consumption, faster switching and improved colour gamut. While advanced fabrication and processing techniques meet some of these new challenges, the complexity and associated costs of manufacturing microLEDs with such requirements have stalled the widespread adoption of microLEDs across various market sectors.
At Kubos Semiconductors we are focused on a material-level solution, using cubic-GaN, to overcome the fundamental technological limitations that have hindered market adoption. This presentation will explain the unique properties of cubic-GaN that make it a material of choice for future visible wavelength LEDs and microLEDs. Furthermore, we will explain how Kubos’ technology can enhance existing device performance and enable RGB wavelength from a common material platform with minimal capital investment and process adjustment, using existing semi-standard silicon toolsets at 200mm and above.
