Abstract

An ultraviolet device packaging structure disclosed by the present invention comprises a chip, a lens and a substrate, the chip is arranged in a light-condensing accommodating hole of the lens, the chip can be conducted with an external element by using a first conduction element, the substrate blocks the accommodating hole, the chip is packaged in a packaging cavity, and the packaging cavity is filled with a protective gas. Inert gases such as nitrogen can be selected as the protective gas, and the chip is prevented from being influenced by the atmosphere, so that the radiation energy of the deep ultraviolet light-emitting diode is improved, and the sterilization and disinfection effects of the deep ultraviolet light-emitting diode are enhanced. Meanwhile, the invention further provides a manufacturing method of the ultraviolet device packaging structure, a eutectic furnace is used for enabling protective gas to enter the space between the substrate and the lens, eutectic welding is achieved between the first conduction element and the lens, the chip and the protective gas are packaged in the packaging cavity, and therefore the influence of the atmosphere on the chip is effectively avoided, and the packaging quality of the ultraviolet device is improved. And the performance of the deep ultraviolet light-emitting diode is improved.

Description

technical field [0001] The present invention relates to the technical field of semiconductor packaging, in particular to an ultraviolet device packaging structure and a manufacturing method. Background technique [0002] Deep ultraviolet light emitting diode (UVC LED) is a high power deep ultraviolet light emitting diode with a wavelength between 220nm and 350nm. The deep ultraviolet light emitting diode has high reliability, long life, fast response, low power consumption, environmental protection, no pollution, small size, etc. Advantages, it is widely used in the fields of sterilization, water purification, medical treatment, high-density optical recording, high color rendering LED lighting and high-speed decomposition and treatment of pollution substances. [0003] It is worth noting that due to the material and structure of the deep ultraviolet light emitting diode chip, the current TE light output of the deep ultraviolet light emitting diode chip is weaker than the sid...
