interesting tidbit from VPEC in Taiwan.....

The gallium arsenide suppliers Visual Photonics Epitaxy (VPE)’s 3D sensor VCSEL arsenide is currently at the sampling state. As the technology barrier is high, the company has spent more than 3 quarters for that, and expects to pass the validation in 2018.

As the second-largest communication epiwafer supplier in the world by capacity only behind IQE, VPEC is one of the few compound semiconductor epiwafer suppliers that operates 6” capacity and owns epiwafer-growing recipes. VPEC is building its Fab 2, aiming to be up and running in 2018 with capacity potential of 20-30 MOCVDs, on top of its current capacity of 41 MOVCDs at Fab 1 where floor space is fully used.
