Abstract
A semiconductor device production method includes providing a first electrode and a second electrode on a rear surface of a substrate where an active region emitting light is formed and providing a laminated object formed of a material less brittle than the substrate at part of a region between the first electrode and the second electrode so as to position directly below the active region; and exposing a plane on which the active region appears by cleavage of the substrate together with the laminated object in a state where the laminated object is located directly above the active region.
