Abstract:
1. A method for manufacturing a chip-type LED comprising: a step of forming metal sheets on the surface and the undersurface of an insulating substrate; a step of removing the metal sheet on the surface side of the insulating substrate at an LED chip mounting position and a fine metal wire connecting position; a step of forming a first recess hole and a second recess hole in the regions from which the metal sheet has been removed such that the first and second recess holes have a depth extending to the metal sheet on the undersurface side of the insulating substrate; a step of forming a conductive layer such that a conductive layer extends over the side faces of the recess holes and the metal sheet at the bottom of the recess holes; a step of forming an Au-containing layer on the surface of the conductive layer by vapor deposition; a step of forming an insulating region; a step of mounting an LED chip on the bottom of the first recess hole; a step of electrically connecting the LED chip and the bottom of the second recess hole using a fine metal wire; a first encapsulating step of encapsulating the first recess hole and part of the fine metal wire in a first transparent resin by a potting process so as to cover the LED chip; and a second encapsulating step of encapsulating the first transparent resin in a second transparent resin by a transfer molding process so as to cover the first transparent resin.
