Abstract:
1. A method of manufacturing a III-V nitride compound semiconductor light emitting element, characterized in that regions of a III-V nitride compound semiconductor light emitting element are formed in a low density dislocation region on a III-V nitride compound semiconductor substrate in which high density dislocation sections are repeatedly arranged while alternating with said low density dislocation regions so that stripe-shaped light emitting regions are made parallel to the direction in which said high density dislocation sections extend; and two scribe lines are subsequently formed so as to sandwich said high density dislocation sections only on the surface of the opposite side from the surface on which said light emitting element regions are formed, and the pitch of said two scribe lines is 100 μm or more, and breaking is then performed to thereby separate chips and remove said high density dislocation sections.
