Abstract
Disclosed is a substrate structure and a method for forming the same, in which a high-quality nitride semiconductor layer may be formed with a reduced stress applied to the nitride semiconductor layer at the growth of the nitride semiconductor layer and also be easily separated from the substrate, and a semiconductor lamination structure using the same and a method for forming the same, and a method for manufacturing a nitride semiconductor using the same. The substrate structure includes a single-crystal substrate heterogeneous from a nitride semiconductor, and a crystallized inorganic thin film having a leg portion configured to contact the substrate to define an integrated cavity between the leg portion and the substrate and an upper surface extending from the leg portion and parallel to the substrate, the crystallized inorganic thin film having the same crystal structure as the substrate.
