PURPOSE: A method for fabricating a surface emission type LED is provided to perform smoothly a distance measurement operation by removing the light emitted from each side of an LED. CONSTITUTION: An N-type epitaxial layer(202) is laminated on an upper surface of a substrate(201). The N-type epitaxial layer(202) and the substrate(201) are etched in a predetermined interval. An isolator layer(203) is deposited on the etched substrate(201) and the etched N-type epitaxial layer(202). The isolator layer(203) is partially removed by performing a patterning process. A P-type ion layer(205) is formed on an upper surface of the predetermined region, which is formed by removing partially the isolator layer(203). |
