As we’re starting to see some penetration in general lighting is mostly in commercial and industrial settings, street lighting and so on, but we haven’t quite reach the inflection point in general lighting, but Jed and many other analysts had to follow the space thing, that is not too far in a distant future. And automotive is the third sub-segment within the LED market. You are starting to see more and more cars, different models of cars with LED lighting both interior and exterior lighting.
I mentioned the large diameters, the importance of large diameter; in the LED market, we’re starting to see the same path of progression that we saw in the semiconductor world, which has started out with small diameter substrates and for economies of scale grew to larger and larger substrates. In the LED market, it started out with two inches, three and four inch substrates are prevailing right now and we’re starting to see some migration to six inch. This is important as we’ll talk about this little further. Rubicon is the market leader in large diameter sapphire. We have about 70% market share in six inch wafers today both in the SoS and LED market.
In the SoS space, for those of you who are not familiar with it, the antenna switch within your smartphone, which controls the send and receive signal historically has been made with gallium arsenide based chips. Our customer came up with the SoS technology, which provides for one single monolithically grown chip that replaces those multiple gallium arsenide chips resulting in smaller form factor, less power usage, because sapphire is such a good insulator eliminates, virtually eliminates the crosstalk associated with some cell phones.
For that reason, our customer is rapidly gaining market share and has been engineering into all of the major smartphones, the Apple and the Samsung and even in the iPad. And we have seen significant growth. Our revenue from this sub-segment has doubled sequentially over the past two quarters going from $2 million at the end of last year to $4 million to $7 million in the last quarter and we expect it to continue to grow throughout this year and into next year.Read the rest of this transcript for free on seekingalpha.com
