Patent ID: 7795053

Claim:
A method for producing a light-emitting device comprising: a step of electrically connecting a first electrode provided on a light-emitting layer of a light-emitting element and a first lead of a lead frame so that the first electrode is opposite to an element mounting part of the first lead, wherein said light-emitting layer is provided on a main surface of a semiconductor substrate; a step of electrically connecting a second electrode provided on a rear surface of the semiconductor substrate, and a second lead of said lead frame; a step of forming a film of joining material made of an alloy or a single metal on the first electrode of said light-emitting element, in advance of the step of electrically connecting the first electrode and said first lead; and a step of forming a pattern on the element mounting part to reduce spreading of said joining material, in advance of the step of electrically connecting the first electrode of said light-emitting element and said first lead, wherein in the step of electrically connecting the first electrode and the first lead, the film of joining material is contacted with the element mounting part under conditions that a temperature of the element mounting part has been raised to not lower than a melting point of the film of joining material, and that a temperature of the light-emitting element is kept at not higher than the melting point of the film of joining material.
