An mold having a sub-micron, or even nano, structure is fabricated. The mold is a porous aluminum oxide mold. With the mold, a sub-micron pattern is easily imprinted on a large surface of a substrate or a LED. No expensive equipment is necessary. The fabricating process is fast and cheap and thus meets the needs of producers.

Method of fabricating porous aluminum oxide mold having sub-micron structure and methods of imprinting to make LEDS using the mold

A structure of light emitting diode (LED) effectively reduces its spectral width. The LED structure is applied in a three color mixing of a backlight module to broaden a color space and to improve a saturation of a color display. A grating structure is used as a waveguide layer to coordinate with the LED structure. The present invention does not affect the original thermo and electrical characteristics of the LED structure and has a simple fabrication method.
