Abstract:
1. A hybrid LED chip, comprising: a first clad layer of P-type semiconductor material; a second clad layer of N-type semiconductor material; an active layer between the first and second clad layers; a first bonding metal layer on the first clad layer; a second bonding metal layer on the second clad layer; a ceramic substrate positioned on and bonded to the first and second bonding metal layers, the ceramic substrate including: a P-type electrode formed by burying a conductive material in the at least one first via hole; an N-type electrode formed by burying a conductive material in the at least one second via hole; an electrode pad configured to connect the second clad layer with the N-type electrode; and an insulating layer configured to insulate the first bonding metal layer and the second bonding metal layer, wherein the first and second via holes in the ceramic substrate are formed in cylindrical shapes, wherein the circumferential surface of each cylindrical shape is provided with an intaglio pattern, and wherein the first bonding metal layer is configured to connect the first clad layer with the P-type electrode.
