NICHIA CORPORATION patent applications published on November 30th, 2023

Summary of the patent applications from NICHIA CORPORATION on November 30th, 2023

NICHIA CORPORATION has recently filed several patents related to the manufacturing and design of light-emitting devices. These patents cover various aspects such as the method of manufacturing light-emitting modules, the structure of light-emitting devices, and the use of specific materials in the production of phosphors.

In terms of manufacturing methods, NICHIA CORPORATION has developed a method that involves providing an intermediate structure with a wiring board, conducting members, and resist layers. The resist layer is then used to expose a portion of the light-emitting element, and bonding members are formed on the conducting members. Another method focuses on detecting and removing defects in a semiconductor layer using lasers.

The patents also describe the structure of light-emitting devices. One patent focuses on a device with a base member, a light-reflective member, and a recess for the light-emitting element. The light-reflective member is positioned to enhance light reflection. Another patent describes a device with a base member, a frame member, and a cover, along with a light-receiving body that receives light emitted by the light-emitting element.

NICHIA CORPORATION has also filed patents related to the use of specific materials in the production of light-emitting devices. These include the use of a wavelength conversion member and a reflecting member to improve light emission, as well as the use of coated magnetic powder made of rare earth-iron-nitrogen-based materials.

Summary of notable applications:

• Method of manufacturing light-emitting modules using an intermediate structure and resist layers.
• Design of light-emitting devices with base members, light-reflective members, and recesses for light-emitting elements.
• Method of manufacturing light-emitting devices using support members and evaluating the electrical characteristics of light-emitting elements.
• Use of coated magnetic powder made of rare earth-iron-nitrogen-based materials in light-emitting devices.
• Design of light-emitting devices with base members, frame members, covers, and light-receiving bodies.
• Method of manufacturing phosphor ceramics using aluminum nitride and manganese gas.
• Use of halophosphate phosphors with low elution amounts of chlorine ions when exposed to hot water.
