Patent ID: 7800096

Claim:
A semiconductor element, comprising: a layered body of a first conductivity type, a light emitting layer, a layered body of a second conductivity type, a constriction layer having a constriction hole, and a first electrode having a lighting hole, wherein an area of said constriction hole is larger than an area of said lighting hole, and the lighting hole and the constriction hole expose a part of said layered body of the second conductivity type, wherein the first electrode and the layered body of the second conductivity type are operatively coupled with one another; a second electrode positioned such that charge traveling between the first and second electrodes passes through the light emitting layer; and a mirror positioned such that the mirror receives light emitted from the light emitting layer that passes through the layered body of the first conductivity type, and the mirror being constructed and arranged to have a high reflection ratio for light having peak wavelengths between 200 nm to 350 nm.
