Abstract:
1. A semiconductor laser manufacturing method for manufacturing a semiconductor laser by cleaning a cleavage plane of a semiconductor laminated structure by a plasma cleaning using a sputtering apparatus, the cleavage plane being to be an end face of a resonator, the method comprising: a first step of placing the semiconductor laminated structure with the cleavage plane in the sputtering apparatus; a second step of introducing a process gas containing a reactive gas and an inert gas into the sputtering apparatus, and then putting the process gas into a plasma state; and a third step of exposing a target material and the cleavage plane to the process gas in the plasma state while no voltage is applied to the target material, causing a reaction of the target material and the reactive gas to form a compound that reflects light of a predetermined wavelength so that a film of the compound is formed on the cleavage plane.
