Abstract:
According to one embodiment, a semiconductor device includes first to third electrodes, and first to third semiconductor regions. The third electrode is separated from the second electrode in a first direction. The first semiconductor region includes a first partial region separated from the first electrode, a second partial region separated from the second electrode, and a third partial region separated from the third electrode. The second semiconductor region includes a fourth partial region positioned between the first electrode and the first partial region, a fifth partial region positioned between the second electrode and the second partial region, and a sixth partial region positioned between the third electrode and the third partial region. The third semiconductor region includes a seventh partial region positioned between the second electrode and the fifth partial region and an eighth partial region positioned between the third electrode and the sixth partial region.

Claim (Index 19):
A method for manufacturing a semiconductor device, comprising:\n removing a portion of a second semiconductor film and a portion of a first semiconductor film to form a first semiconductor region from the first semiconductor film by using a mask provided on a portion of a stacked body including the first semiconductor film and the second semiconductor film, the first semiconductor film including Al x1 Ga 1-x1 N (0<x1\u22641), the second semiconductor film including Al x2 Ga 1-x2 N (0\u2264x2<1 and x2<x1) and being provided on the first semiconductor film, the first semiconductor region including first to third partial regions, a portion of the first partial region being positioned between the second partial region and the third partial region in a first direction, the first direction crossing a second direction, the second direction being from the first semiconductor film toward the second semiconductor film; forming a fifth partial region and a sixth partial region, the fifth partial region including Al x2 Ga 1-x2 N (0\u2264x2<1 and x2<x1) and being positioned on the second partial region, the sixth partial region including Al x2 Ga 1-x2 N (0\u2264x2<1 and x2<x1) and being positioned on the third partial region; forming a seventh partial region and an eighth partial region, the seventh partial region including Al x3 Ga 1-x3 N (0<x3\u22641 and x2<x3) and being positioned on the fifth partial region, the eighth partial region including Al x3 Ga 1-x3 N (0<x3\u22641 and x2<x3) and being positioned on the sixth partial region; removing the mask; forming an insulating film on another portion of the second semiconductor film; and forming a first electrode, a second electrode, and a third electrode, the first electrode being positioned on the insulating film, the second electrode being positioned on the seventh partial region, the third electrode being positioned on the eighth partial region.
