REVERSELY-INSTALLED PHOTONIC CRYSTAL LED CHIP AND METHOD FOR MANUFACTURING SAME |
摘要 |
A method of fabricating a flip-chip photonic-crystal light-emitting diode (LED) is disclosed. The method includes the steps of: providing an initial substrate including an epitaxial-growth surface and a light-output surface; performing a nanoimprint process on the epitaxial-growth surface of the initial substrate to form a nano-level patterned substrate; forming a flip-chip LED structure on the epitaxial-growth surface of the nano-level patterned substrate; and performing a nanoimprint process on the light-output surface of the nano-level patterned substrate to form the flip-chip photonic-crystal LED. The formation of the photonic-crystal structure on the light-output surface results in enhanced LED light extraction and emission efficiency. |
