As the old semiconductor industry saying goes “if it can be made on silicon it will be made on silicon”. Will this prediction turn true for the solid state lighting industry as well? For many years, LED-on-Si has been touted as “the next big thing” in LED manufacturing. Similarly, GaN has been considered the perfect substrate for high brightness LEDs. However, efforts have so far failed to come to fruition and transform the industry. But in the last 18 months, many established LED manufacturers and startup companies alike have announced impressive results showing that mass manufacturing of LEDs on 6” or 8” silicon substrates might finally be around the corner. Similarly, some companies have started manufacturing commercial LEDs on GaN.
In this webcast we will try to decode the most recent announcements and understand what additional progresses are required for those technologies to meet both the challenges of mass manufacturing and the solid state lighting industry roadmap. We will look at cost of ownership vs. the established sapphire based LED manufacturing process and identify the conditions for sucess. We will try to understand if Si or GaN can displace the legacy substrates or will be limited to certain types of devices and market segments and how much changes this might trigger in the LED supply chain.
