Abstract:
A nitride semiconductor ultraviolet light emitting device  1  is configured such that a nitride semiconductor ultraviolet light emitting element  10  is mounted on a base  30  by flip-chip mounting and sealed with an amorphous fluororesin whose terminal functional group is perfluoroalkyl group. The nitride semiconductor ultraviolet light emitting element  10  includes a sapphire substrate  11 , a semiconductor laminated portion  12  of an AlGaN-based semiconductor laminated on a front surface of the sapphire substrate  11 , an n electrode  13 , a p electrode  14  and a back surface covering layer  15  which is formed on a back surface of the sapphire substrate  11  and transmits ultraviolet light. The back surface covering layer  15  has apertures  16  through which a part of the back surface of the sapphire substrate  11  is exposed, the apertures  16  is uniformly dispersed or distributed on the back surface of the sapphire substrate, a cross-sectional shape of the apertures  16  vertical to the back surface of the sapphire substrate  11  has a portion where an aperture width of a part close to the back surface is wider than an aperture width of a part far from the back surface, and the amorphous fluororesin covers the front surface of the back surface covering layer  15  and fills insides of the apertures  16.

Claim (Index 5):
The nitride semiconductor ultraviolet light emitting device according to  claim 1 , wherein\n a structural unit of polymer or copolymer that forms the amorphous fluororesin has a fluorine-containing aliphatic cyclic structure.
