Patent ID: 8753907

Claim:
A method for manufacturing a semiconductor light emitting device, comprising: preparing a metal plate including a plurality of first frame portions and a plurality of second frame portions, the first frame portions and the second frame portions being alternately arranged, each respective first frame portion having a light emitting element fixed thereto on a front surface side of the metal plate, the light emitting element being connected to an adjacent one of the second frame portions via a metal wire, the adjacent one of the second frame portions being spaced from the respective first frame portion; molding a first resin on the metal plate, the first resin covering the first frame portions, the second frame portions, and the light emitting elements; forming a groove in the first resin by cutting the metal plate and the first resin from a back surface side of the metal plate, the groove having sidewalls that slope such that a width of the groove narrows with increasing distance away from the back surface side of the metal plate; filling the groove with a second resin; and forming a resin package that includes one first frame portion having a light emitting element fixed thereto and one adjacent second frame portion by cutting through the second resin in the groove.
