摘要:
A semiconductor light emitting device manufacture method is provided which can manufacture a semiconductor light emitting device of high quality. A first substrate of an n-type ZnO substrate is prepared. A lamination structure including an optical emission layer made of ZnO based compound semiconductor is formed on the first substrate. A p-side conductive layer is formed on the lamination structure. A first eutectic material layer made of eutectic material is formed on the p-side conductive layer. A second eutectic material layer made of eutectic material is formed on a second substrate. The first and second eutectic material layers are eutectic-bonded to couple the first and second substrates. After the first substrate is optionally thinned, an n-side electrode is formed on a partial surface of the first substrate.
