Abstract
A method for fabricating a compound semiconductor epitaxial structure includes the following steps. Firstly, a first compound epitaxial layer is formed on a substrate. Then, a continuous epitaxial deposition process is performed to form a second compound epitaxial layer on the first compound epitaxial layer, so that the second compound epitaxial layer has a linearly-decreased concentration gradient of metal. Afterwards, a semiconductor material layer is formed on the second compound epitaxial layer.
