Abstract
The present application discloses a light-emitting apparatus comprising a first light-emitting semiconductor stack, a first intermediate layer formed on the first light-emitting semiconductor stack and a second light-emitting semiconductor stack formed on the first intermediate layer. The first intermediate layer comprises a first conductive semiconductor layer, a second conductive semiconductor layer and an intermediate region. The intermediate region has a discontinuous structure located between the first conductive semiconductor layer and the second conductive semiconductor layer.
