A recently awarded patent (US 9,190,616) describes materials enabling significant increase and control of key optical constants: the refractive index (at 1.70) and extinction coefficient, optical transmission – while still retaining excellent dielectric performance and solid environmental robustness. These properties are essential for device and process design factors fabless designers, IMD and OEM brand owners in semiconductor optoelectronics industry. 
PiBond’s molecularly designed organo-silane and siloxane polymers have found many commercial uses in advanced semiconductor devices such as smartphone imaging sensors, quantum dot displays as well in the most advanced lithography processes. The company’s factory in Espoo, Finland yields specialty siloxane and metal oxide polymers with one of the highest purities in the industry.
