Patterned Sapphire Substrate (PSS)

We use an inexpensive in-house process using Blodgett-Langmuir process to create nano-pillars in sapphire leading to creation of patterned sapphire substrates.

This enables the this Co. to manufacture our own patterned substrates, while constant research is on for optimizing the pattern to extract maximum light out while taking advantage of growth of relaxed crystal in the wafer.
