Patent ID: 7816694

Claim:
A light emitting semiconductor device comprising: a substrate; a plurality of flip chips, electrically connected on the substrate; a heat conductive board, having a protruding portion used to support the substrate; an insulating board, having a plurality of connecting pads and an opening, wherein the protruding portion is sheathed in the opening so to expose the substrate mounted on the heat conductive board; and the exposed substrate is electrically connected to the connecting pads, wherein the substrate comprises: a plurality of mounting pads, on which a plurality of bumps are deposited to electrically connect the mounting pads with the flip chips; and a plurality of wires, each of which has a first end electrically connected to one of the mounting pads and a second end electrically connected to one of the connecting pads; and at least one mounting chip that is mounted on the substrate with its rear surface by a surface mounting process, wherein the mounting chip is deposited on the peripheral of the matrix consisted of the flip chips.
