Subject: Automotive LED-using a thermal conductivity better performance of the substrate materials
2010-01-08



Efficient light extraction efficiency of the method: Sapphire substrates for epitaxial growth of GaN-based blue and green LED, the removal of non-conducting sapphire substrate at the same time, using a thermal conductivity better performance of the substrate materials (such as silicon, copper, etc.) so that the device heat dissipation better, and avoid the double-sided electrode device current congestion problems, and significant savings in chip area, in the high-power device applications have significance.
