Ultraviolet light emitting device using metal non-bondable amorphous fluororesin molding compound |
摘要 |
An ultraviolet light emitting device having high quality and high reliability is provided by preventing deterioration of electrical characteristics which is associated with an ultraviolet light emission operation and caused by a sealing resin. The ultraviolet light emitting device is an ultraviolet light emitting device including: an ultraviolet light emitting element (2) formed of a nitride semiconductor; and an ultraviolet-transparent sealing resin (3) covering the ultraviolet light emitting element (2), wherein at least a specific portion (3a) of the sealing resin (3), which is in contact with pad electrodes (18) and (17) of the ultraviolet light emitting element (2), is a first type amorphous fluororesin, and a terminal functional group of a polymer or a copolymer that forms the first type amorphous fluororesin is a nonreactive terminal functional group which is not bondable to a metal that forms the pad electrodes (16) and (17). |

1. An ultraviolet light emitting device comprising: an ultraviolet light emitting element formed of a nitride semiconductor; and an ultraviolet-transparent sealing resin covering the ultraviolet light emitting element, wherein
at least a specific portion of the sealing resin, which is in direct contact with a pad electrode of the ultraviolet light emitting element, is a first type amorphous fluororesin, and a terminal functional group of a polymer or a copolymer that forms the first type amorphous fluororesin is a nonreactive terminal functional group which is not bondable to a metal that forms the pad electrode. |
