    • PURPOSE: A nitride based semiconductor device and a method for manufacturing thereof are provided to increase the mass production efficiency of a semiconductor device with the increase of reverse internal pressure in a device by preventing a reverse leak current. CONSTITUTION: A base substrate(110) is formed into a PN junction structure. The base substrate is formed by welding a first type semiconductor layer(112) and a second type semiconductor layer(114) to the top and bottom. A buffer layer(118) is formed on the base substrate. The buffer layer reduces defect due to lattice mismatch between the base substrate and an epitaxial-growth film(120). The epitaxial-growth film includes a first nitride film(122) and a second nitride film(124) which are successively laminated on the base substrate.
    • 目的:提供一种氮化物基半导体器件及其制造方法,通过防止反向泄漏电流,通过设备中的反向内部压力的增加来提高半导体器件的批量生产效率。 构成:基底(110)形成为PN结结构。 基底基板通过将第一类型半导体层(112)和第二类型半导体层(114)焊接到顶部和底部而形成。 在基底基板上形成缓冲层(118)。 缓冲层减少由于基底衬底和外延生长膜(120)之间的晶格失配引起的缺陷。 外延生长膜包括依次层压在基底基板上的第一氮化物膜(122)和第二氮化物膜(124)。
