Abstract:
A nitride semiconductor ultraviolet light-emitting element  1  comprises a sapphire substrate  10  and an element structure part  20  formed on a main surface  101  of the substrate  10 . In the substrate  10 , in a first portion  110  extending from the main surface  101  by a first distance, a sectional area of a cross section parallel to the main surface  101  continuously increases with distance from the main surface  101 , and in a second portion  120  extending from a side opposite to the main surface  101  by a second distance, a sectional area of a cross section parallel to the main surface  101  continuously increases with distance from the side opposite to the main surface  101 . The sum of the first distance and the second distance is equal to or less than the thickness of the substrate  10.

Claim (Index 12):
A nitride semiconductor ultraviolet light-emitting element, comprising:\n a sapphire substrate; and an element structure part including a plurality of AlGaN-based semiconductor layers stacked on a main surface of the substrate, the element structure part emitting light whose central emission wavelength is 365 nm or less upon energization, wherein, in the substrate, in a first portion extending from the main surface by a first distance, a sectional area of a cross section parallel to the main surface continuously increases with distance from the main surface, in a second portion extending from a side opposite to the main surface by a second distance, a sectional area of a cross section parallel to the main surface continuously increases with distance from the side opposite to the main surface, and a sum of the first distance and the second distance is equal to or less than a thickness of the substrate, and wherein, on the side opposite to the main surface of the substrate, a surface parallel to the main surface exists.
