Thermally Controlled Rotational Grinding of Sapphire Wafers for Highly Efficient Manufacturing of Modern White LED Light Sources (ThermoGrind)
Date du début: 1 oct. 2009, Date de fin: 31 janv. 2012,
The market for discrete light emitting diodes (LEDs) is very fast growing. Basic materials for white and blue LEDs are wafers of Silicon Carbide (SiC) and Sapphire (Al2O3). Today European enterprises, most of them SMEs, hold less than 5% of worldwide wafer production due to high production costs compared to the main producers Russia, USA and Japan.The most time consuming and therefore expensive pr ...
