Abstract:
1. A semiconductor light-emitting device package structure, comprising: a substrate thereon defining a top surface and a bottom surface, a first recess being formed on the top surface, a second recess being formed on the bottom surface, and the second recess being passed through and linked together with the first recess, a protrusion being formed on the top surface along the edge of the first recess, a plurality of outer electrodes being disposed on the top surface, a shoulder is formed between the first recess and the second recess; a flat sub-mount constituted by silicon linking to the second recess and thereon defines a respective first surface and a respective second surface, the flat sub-mount being embedded in the second recess such that the first surface of said flat sub-mount is partially exposed within the first recess, the shoulder thereon defining a lower surface which faces toward the first surface of the flat sub-mount, an adhesion paste is coated on the shoulder to assist the bonding of the first surface of the flat sub-mount and the shoulder without electrical connection through the adhesion paste, wherein no electrode is formed on the lower surface of the shoulder and the second surface of the flat sub-mount is substantially parallel to the bottom surface of the substrate; a plurality of semiconductor light-emitting dies, wherein each of the semiconductor light-emitting dies comprises a bottom portion and a inter electrode, the plurality of semiconductor light-emitting dies being mounted to the first surface of the flat sub-mount partially exposed within the first recess; and a package material filled into the protrusion to cover the plurality of semiconductor light-emitting dies.
