Abstract
Disclosed herein are a III-N semiconductor structure manufactured by growing a III-N material on a superlattice structure layer, formed of AlGaN and InAlN materials, which serves as a buffer layer, and a method for manufacturing the same. The disclosed III-N semiconductor structure includes: a substrate including a silicon material; a seed layer formed on the substrate and including an aluminum nitride (AlN) material; a superlattice structure layer formed by sequentially depositing a plurality of superlattice units on the seed layer; and a cap layer formed on the superlattice structure layer and including a gallium nitride (GaN) material, wherein the superlattice units are each composed of a first layer including an AlxGa1−xN wherein 0≤x≤1 and a second layer including an InyAl1−yN wherein 0y≤0.4.
