Abstract:
1. A manufacturing method of a semiconductor light-emitting element in a sputtering apparatus including a target placed at a lower portion in a chamber, a substrate placed at an upper portion in the chamber, and a heating member placed above the substrate in the chamber, the target being any one of a group III element, a mixture including a group III element, and a compound including a group III element, the substrate being arranged in such a manner that one surface thereof faces the target, the method comprising: a substrate heating step for heating the substrate, the substrate being heated by absorbing electromagnetic waves having wavelengths including 4 μm or more, the electromagnetic waves being radiated from the heating member; and a group III nitride layer forming step for forming a group III nitride layer on the heated substrate by plasma generated in an atmosphere including nitrogen between the target and the substrate, wherein the substrate is sapphire, and wherein a temperature to which the substrate is heated by absorbing the electromagnetic waves is 500 degrees C. or more and less than 1500 degrees C.
