    摘要: A nitride semiconductor device includes a semiconductor substrate, and a nitride semiconductor layer formed on the semiconductor substrate. The semiconductor substrate includes a normal region and an interface current block region surrounding the normal region. The nitride semiconductor layer includes an element region and an isolation region surrounding the element region. The element region is formed over the normal region. The interface current block region contains impurities, and forms a potential barrier against carriers generated at an interface between the nitride semiconductor layer and the semiconductor substrate.
