According to Dow Electronic Materials, in 2011, the company's sapphire wafers, 0.5*0.5 chips and phosphors all grew by more than 20%, driven by a wide range of LED applications, including transportation, mobile communications, Display and TV, solid state lighting, etc.
Dow materials believe that the new materials will be the key to driving the reduction of unit cost and lumen improvement of LED lighting, including color rendering index, color uniformity, thermal stability, etc., are the most important performance indicators of LED, and also maximize the lumens per watt. The essential.
To advance the performance of next-generation solid-state lighting, Dow Chemical has improved the LED industry chain on a variety of products, particularly in substrates, wafers, die and packaging. At present, Dow's LED products supply key processes such as lithography, chemical mechanical polishing (CMP) and metallization required in LED manufacturing processes, phosphors required for high-profile LED packaging, and The company is widely used in organometallic chemical vapor deposition (MOCVD) leads and epitaxial growth techniques.
Dow's MACHPLANER MS2000 silica-based slurry enhances the flatness of sapphire wafers required in LED manufacturing. In addition, Dow has used more than 50 years of metallization experience in the LED manufacturing industry. Its material portfolio includes SILVER GLO and SILVERJET electroplated silver materials and materials in research and development to meet the market's high light extraction rate. Reflective energy metal material requirements.
After the acquisition of Lightscape Materials Inc., Dow has begun offering carbonitride phosphors that enable LEDs to produce a wide range of white light and adjust color for the applications they need. The material has good quantum efficiency and provides the high luminescence emission technology required to demonstrate BLU and illumination to achieve top thermal quenching performance. Dow said it has applied for patent protection for innovative technologies. 
Due to the rapid growth of LED in recent years, Dow's Dow Electronic Materials business group announced that it will integrate its product portfolio and strengthen its support for lighting technology to cope with current and future solid-state lighting markets. LED demand in the middle.
