Abstract

Provided is a hetero-substrate that may include a base substrate, a buffer layer disposed on the base substrate, and a first semiconductor layer disposed on the buffer layer, the first semiconductor layer including a nitride semiconductor. A defect blocking layer is disposed on the first semiconductor layer. The defect blocking layer may include a plurality of metal droplets. A second semiconductor layer may be disposed on the defect blocking layer, the second semiconductor layer including a nitride semiconductor.
