Abstract
A semiconductor structure is provided. The semiconductor structure includes a substrate, an epitaxial layer, multiple field plate structures, multiple shielding layers, an upper electrode layer, and a lower electrode layer. The epitaxial layer is disposed on the substrate. The field plate structures include a first field plate structure and a second field plate structure respectively disposed in a first unit and a second unit of the semiconductor structure. The shielding layers are disposed between the bottom portions of the field plate structures and the epitaxial layer. The upper electrode layer covers the field plate structures. The upper electrode layer is separated from the epitaxial layer in the first unit and is in direct contact with the epitaxial layer in the second unit. The lower electrode layer is disposed under the substrate and opposite to the epitaxial layer.
