Abstract
A method of manufacturing a light emitting device includes: providing a wafer including a conductive first substrate, a laser element structure on an upper side of the first substrate, and an upper surface electrode on an upper surface of the element structure; bonding the wafer to a second substrate at an upper surface electrode side of the wafer; removing a portion of the first substrate to reduce a thickness of the wafer; forming a lower surface electrode on a lower surface of the first substrate at which the removing of the portion of the first substrate has been performed; singulating the wafer to obtain a laser element; and mounting the laser element on a submount such that the lower surface electrode faces the submount.
