Abstract
A semiconductor structure is provided. The semiconductor structure includes a substrate, a buffer layer, a barrier layer, a dielectric layer, a source structure, and a drain structure. The buffer layer is disposed on the substrate. The barrier layer is disposed on the buffer layer. The dielectric layer is disposed on the barrier layer. The passivation layer is disposed on the dielectric layer. The source structure and the drain structure are disposed on the passivation layer.
