Patent ID: 8450764

Claim:
A semiconductor light-emitting apparatus comprising: a semiconductor light-emitting device having an electrode formation plane and comprising a p-electrode and a pair of n-electrodes with the p-electrode therebetween, formed in the electrode formation region; a supporting board supporting the light-emitting device and comprising an insulating substrate which has an electrode formation plane corresponding to the electrode formation plane of the light-emitting device and on which a positive and a pair of negative electrodes are formed in the electrode formation plane of the supporting board, electrically isolated from each other and opposing to the p- and n-electrodes on the light-emitting device, respectively; and bonding members bonding the p-electrode and the n-electrodes on the light-emitting device with the positive electrode and the negative electrodes on the supporting board, respectively; the p-electrode on the light-emitting device being formed substantially entirely on the electrode formation plane of the light-emitting device, except for those portions on which the n-electrodes are formed and being eutectically bonded with the positive electrode of the supporting board; the positive electrode of the supporting board being formed within a width region of the p-electrode and narrower in width than the width of the p-electrode, in a cross-section along a line extending through the pair of n-electrodes of the light-emitting device; the negative electrodes of the supporting board opposing to the n-electrodes of the light-emitting device, respectively, with the same widths, or with that side face of each of the negative electrodes which faces the positive electrode being retracted outwardly from that side face of each of the n-electrodes which faces the p-electrode.
