    The characteristics required by LED substrate material
    POSTED ON AUGUST 20, 2013 BY ADMIN IN LED CHIP, LED KNOWLEDGE WITH THERE ARE NO COMMENTS
    The quality of LED epitaxial wafers depends on the substrate material and the epitaxial technology; it’s the cornerstone of semiconductor lighting industry. Different substrate materials require different epitaxial growth technology, chip processing technology and device packaging technology. Substrate material determines the roadmap for semiconductor lighting technology. The quality substrate material depends on the following eight items:
    1) Good conductivity: can be made up and down layers.
    2) Chemical characteristic is stable: can not be decomposed and corroded in the epitaxial growth temperature and the atmosphere.
    3) The crystal structure of substrate material with the same or similar as epitaxial material, crystal constant with less mismatch, good crystallinity and small defect density.
    4) Low price.
    5) Good optical performance, the substrate absorbs less light emitted by the device.
    6) Large size, generally require no less than 2 inches in diameter.
    7) Good thermal properties, including thermal conductivity and thermal mismatch.
    8) Good mechanical properties: devices processed easily, including thinning, polishing and cutting, etc.
