Patent ID: 8877530

Claim:
A method for preparing a semiconductor light-emitting device, the method comprising: (a) preparing a first wafer in which semiconductor multi-layered light-emitting structure is disposed on an upper part of an initial substrate; (b) preparing a second wafer which is a supporting substrate; (c) bonding the second wafer on an upper part of the first wafer; (d) separating the initial substrate of the first wafer from a result of the bonding; and (e) fabricating a single-chip, wherein the supporting substrate is formed by successively disposing a selected supporting substrate, a sacrificial layer and a heat-sink layer, wherein the fabricating of the single-chip comprises: (e1) attaching a temporary supporting substrate in an opposite direction of the supporting substrate for preparing a semiconductor light-emitting device, (e2) separating the selected supporting substrate from the heat-sink layer, (e3) bonding a third supporting substrate to the heat-sink layer, and (e4) removing the temporary supporting substrate from the semiconductor multi-layered light-emitting structure.
