ABSTRACT:
A semiconductor light-emitting element10includes a silicon single crystal substrate20having a first and a second surfaces20a, 20bin head-tail relationship with each other, a GaN-based semiconductor laminate40formed on a selected region of the first surface with a predetermined conductive intermediate layer25interposed therebetween, a first electrode layer51having a portion in contact with an uppermost layer of the GaN-based semiconductor laminate40and insulated from the monocrystal silicon substrate, and a second electrode layer52formed on a suitable portion of the monocrystal silicon substrate. The monocrystal silicon substrate20is formed with a light guide30for directing light emitted from the GaN-based semiconductor laminate40toward the second surface20b.
