Abstract:
Provided is a deep ultraviolet LED with a design wavelength λ, including a reflecting electrode layer, an ultra-thin metal layer, and a p-type contact layer that are arranged in this order from a side opposite to a substrate; and a hemispherical lens bonded to a rear surface of the substrate on a side of the p-type contact layer, the hemispherical lens being transparent to light with the wavelength λ. The refractive index of the hemispherical lens is greater than or equal to the average value of the refractive index of the substrate and the refractive index of air and is less than or equal to the refractive index of the substrate. The hemispherical lens has a radius that is greater than or equal to the radius of an inscribed circle of the substrate and is about equal to the radius of a circumscribed circle of the substrate.

Claim (Index 43):
A method for manufacturing the deep ultraviolet LED according to  claim 31 , comprising:\n a step of preparing a stacked structure including a highly reflecting electrode layer, an ultra-thin metal layer, and a transparent p-AlGaN contact layer that are arranged in this order from a side opposite to a sapphire substrate; a step of preparing a quartz hemispherical lens with a radius that is greater than or equal to a radius of a circumscribed circle of the substrate; and a step of bonding the hemispherical lens to a rear surface of the substrate, wherein: a method of the bonding is selected from surface activated bonding (SAB), atomic diffusion bonding (ADB), bonding performed after modifying a surface with atmospheric-pressure plasma or ozone gas, or bonding performed with an adhesive that is transparent to light with the design wavelength, so that scattering and absorption of light at a bonded interface are suppressed.
