ABSTRACT:
A light emitting semiconductor device is provided which comprises a semiconductor chip and a sub-mount assembled with the semiconductor chip. The semiconductor chip includes a light-permeable insulating substrate and a laminate of semiconductor layers formed on a support surface of the insulating substrate for generating light to be emitted from a tail surface of the substrate. The sub-mount includes an electrically conductive substrate having a mounting surface facing the support surface of the insulating substrate. The mounting surface of the conductive substrate is formed with at least one auxiliary anode electrode which is electrically connected to the conductive substrate and an anode electrode of the semiconductor chip. The mounting surface of the conductive substrate is also formed with at least one auxiliary cathode electrode which is insulated from the conductive substrate but electrically connected to a cathode electrode of the semiconductor chip.
