This Korean outfit gave several talks, including a fascinating account of how to produce LEDs spanning a vast colour range on pyramid-shaped nanostructures. Vertical variants producing promising results were reported by Osram Opto Semiconductors, and this company also revealed its progress in green lasers.
However, these companies were not joined by other big names in the opto-field, such as Lumileds, Cree and Nichia, who didn’t speak at the meeting. In my opinion, it was their absence that prevented the conference from being a truly great one, like it was in Las Vegas in 2007, when on one memorable afternoon several of the big LED chipmakers went head-to-head as they detailed their latest lab results.
Input from companies was also lacking on the laser diode front, with the likes of Nichia, Rohm and Sumitomo not giving talks at the conference. And unfortunately GaN RF manufacturers were even thinner on the ground.
Given that the vast majority of academic research presented at the conference targets improvements to device performance, I feel that the lack of talks by the leading chipmakers is not healthy. That is because presentations by the big firms detailing state-of-the-art performance and potential roadblocks for further success will motivate many academics and show them areas where tomorrow’s research can have commercial impact.
The absence of the GaN RF makers is not a really big concern for me, because these firms do get together at other conferences, such as CS Europe and CS Mantech. But what about the LED chipmakers that will together drive a revolution in general illumination?
As far as I’m aware, these firms don’t have a conference that focuses at the chip level on LED manufacturing. And judging by the evolution of the silicon industry, really high volume production requires such gatherings, which can play a role in agreeing standards and helping to improve manufacturing processes.
It will be interesting to see what happens. And while I wait, I’ll look forward to hearing many great talks at the next ICNS, which will be held in Washington DC in 2013.

I’ve just returned from the ninth International Conference on Nitride Semiconductors, which was, without doubt, a very good meeting.
You know that a strong programme has been put together when you want to be in two places at once. And that’s how I felt on several occasions, including the time I went to an excellent talk from Toyota on a pair of devices that it is developing for delivering electrical conversion in hybrid electric vehicles. While I was there, I had to miss what was certain to be an interesting presentation from Samsung on their development of GaN LEDs on 8-inch silicon.
