Abstract
The present invention provides a manufacturing method of a semiconductor structure and a semiconductor structure. The manufacturing method includes: providing a substrate; forming an amorphous layer on the substrate, wherein the amorphous layer includes a plurality of patterns to expose part of the substrate; forming a metal nitride layer on the amorphous layer; removing the amorphous layer to form a plurality of cavities between the substrate and the metal nitride layer; removing the substrate to form the semiconductor structure. In the present invention, an amorphous layer is formed on the substrate, and a metal nitride layer is formed on the amorphous layer. The amorphous layer can inhibit slip or dislocation during epitaxial growth, thereby improving the quality of the metal nitride layer and improving the performance of the semiconductor structure, while the metal nitride layer can realize self-supporting.
