Title:
NITRIDE SEMICONDUCTOR ULTRAVIOLET LIGHT EMITTING DEVICE AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2017/208535
Kind Code:
A1
Abstract:
Provided is an ultraviolet light emitting device having high quality and high reliability, which is prevented from deterioration in the electrical characteristics caused by a photochemical reaction due to use of a non-binding amorphous fluororesin and from decomposition of the amorphous fluororesin and the like, while also being prevented from separation of the amorphous fluororesin. A nitride semiconductor ultraviolet light emitting device 1 is provided with: a base 30; a nitride semiconductor ultraviolet light emitting element which is flip-chip mounted on the base 30; and an amorphous fluororesin 40 that is in direct contact with the nitride semiconductor ultraviolet light emitting element so as to cover the nitride semiconductor ultraviolet light emitting element. The nitride semiconductor ultraviolet light emitting element is provided with: a sapphire substrate 11; a plurality of AlGaN semiconductor layers 12 which are laminated on a main surface of the sapphire substrate 11; an n-electrode 13; and a p-electrode 14. The terminal functional group of the amorphous fluororesin 40 is a perfluoroalkyl group; and the amorphous fluororesin 40 enters into a recess that is formed in a lateral surface of the sapphire substrate 11.
