Abstract
A method for producing a light emitting diode includes the steps of: forming a first semiconductor multilayer on a first semiconductor substrate having a first conductivity type; forming a light emitting layer on the first semiconductor multilayer; forming a second semiconductor multilayer; disposing a second substrate which is transparent to light emitted from the light emitting layer on the second semiconductor multilayer; and bonding the second substrate and the second semiconductor multilayer through direct bonding with heating a vicinity of an interface between the second substrate and the second semiconductor multilayer.
