Method for manufacturing vertically-structured semiconductor light emitting device

摘要

The present invention is related to a supporting substrate for manufacturing vertically-structured semiconductor light emitting device and a vertically-structured semiconductor light emitting device using the same, which minimize damage and breaking of a multi-layered light-emitting structure thin film separated from a sapphire substrate during the manufacturing process, thereby improving the whole performance of the semiconductor light emitting device. The supporting substrate for manufacturing the vertically-structured semiconductor light emitting device of the present invention comprises: a selected supporting substrate formed of a material having a difference of thermal expansion coefficient of 5 ppm or less from a sapphire substrate on which a multi-layered light-emitting structure thin film comprising a Group III-V nitride-based semiconductor is laminated; a sacrificial layer formed on the selected supporting substrate; a thick metal film formed on an upper part of the sacrificial layer; and a bonding layer formed on an upper part of the thick metal layer and formed of a soldering or brazing alloy material.
