Abstract
A light emitting semiconductor bonding structure includes a structure formed by bonding a substrate onto a light emitting semiconductor. The substrate is a structure containing electric circuits. The ohmic contact N electrode layer and P electrode layer are formed on the N-type contact layer and the P-type contact layer of the light emitting semiconductor respectively. A first metallic layer and a second metallic layer are formed on the surface of the substrate by means of immersion plating or deposition. The metallic layers are connected electrically to the corresponding electric signal input/output nodes of the electric circuit of the substrate. The first metallic layer and the second metallic layer are bonded onto the N electrode layer and the P electrode layer respectively through supersonic welding, and as such the light emitting semiconductor is bonded onto the substrate, and thus realizing the electric connection in-between.
