Abstract: Provided is a power device. The power device may include a two-dimensional electron gas (2-DEG) layer in a portion corresponding to a gate electrode pattern since a second nitride layer is further formed on a lower portion of the gate electrode pattern after a first nitride layer is formed and thus, may be capable of performing a normally-OFF operation. Accordingly, the power device may adjust generation of the 2-DEG layer based on a voltage of a gate, and may reduce power consumption. The power device may regrow only the portion corresponding to the gate electrode pattern or may etch a portion excluding the portion corresponding to the gate electrode pattern and thus, a recess process may be omissible, a reproducibility of the power device may be secured, and a manufacturing process may be simplified.

Abstract: A nitride-based semiconductor device is provided. The nitride-based semiconductor device may include an aluminum silicon carbide (AlSixC1-x) pre-treated layer, and thus may ease a stress in a nitride semiconductor layer caused by a difference in properties, for example, a lattice constant and a coefficient of expansion, between the substrate and the nitride semiconductor layer formed on the substrate. Accordingly, an incidence of cracks created in the nitride semiconductor layer may be minimized and a surface roughness of the nitride semiconductor layer may be improved and thus, stability and performance of the nitride-based semiconductor device may be improved. The nitride-based semiconductor device may include a grade AlGaN layer of which an aluminum (Al) content gradually decreases from the substrate and thus, an incidence of cracks created in the nitride semiconductor layer may be minimized and the nitride semiconductor layer having a stable structure may be formed.
