Using sapphire glass on chips. Should see benefits down the road.

Meanwhile, Rubicon is off more than 40% from its 52-week high as the sapphire wafer maker has yet to benefit from an increase in demand. That said, the company's revenue is expected to increase 56% this year as developmental costs transition to production revenue.

The only problem is that sapphire costs remain high, and Rubicon's large inventory has led to unexpected charges for the company, in part due to a rise in samples like the ones with Samsung. Like GT Advanced, if large-scale production becomes a reality, then Rubicon has a lot to gain in this space.
