Abstract:
A nitride semiconductor structure includes a substrate, a nitride semiconductor layer, and a buffer stack layer between the substrate and the nitride semiconductor layer. The buffer stack layer includes a plurality of metal nitride multilayers repeatedly stacked, wherein each of the metal nitride multilayers consists of a first, a second, and a third metal nitride thin films in sequence, or consists of the first, the third, the second, and the third metal nitride thin films in sequence. The aluminum concentration of the first metal nitride thin film is higher than that of the third metal nitride thin film, and the aluminum concentration of the third metal nitride thin film is higher than that of the second metal nitride thin film.

Claim (Index 18):
The nitride semiconductor structure according to  claim 11 , wherein a material of the substrate comprises silicon.
