Claim Text:
1. A nitride semiconductor layer spreading along a first surface, the nitride semiconductor layer comprising: a first region, wherein a length of the first region in a first direction parallel to the first surface is longer than a length of the first region in a second direction parallel to the first surface, wherein the second direction is perpendicular to the first direction; and a second region arranged with the first region in the second direction, wherein a length of the second region in the first direction is longer than a length of the second region in the second direction, wherein the nitride semiconductor has a c-axis that is tilted with respect to the second direction for the first region and the second region, wherein the c-axis intersects a third direction, wherein the third direction is perpendicular to the first direction and the second direction, and wherein the c-axis is tilted with a plane including the second direction and the third direction.
