Abstract
A method for fabricating a semiconductor light emitting device is provided. The method involves: forming a light emitting construct including a p-type electrode on a n-type substrate; etching a bottom surface of the n-type substrate; and forming an n-type electrode on the etched bottom surface of the n-type substrate. The bottom surface of the n-type substrate is wet or dry etched. The bottom surface of the n-type substrate is free from damage so that stable attachment of the etched bottom surface of the n-type substrate is ensured with improved properties of the light emitting device which may be a semicoductor laser diode.
