FABRICATION METHOD OF LIGHT EMITTING DEVICE

摘要

PURPOSE: A light emitting device manufacturing method is provided to reuse a sapphire substrate by separating a sapphire substrate. CONSTITUTION: A first layer of a first conductivity type semiconductor layer(120) is formed on a first substrate. A bonding layer is formed on the first layer and a second substrate is formed. The first substrate is separated. A third substrate is formed on the first layer which is exposed by separating the first substrate. The second substrate and the bonding layer are separated. An active layer(150) and a second conductivity type semiconductor layer(160) are formed on the first layer which is exposed by separating the second substrate.
