Assignee: NISSAN MOTOR CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a substrate;
a main groove formed in a main surface of the substrate extending along a longitudinal direction, the main groove having a first terminal end and a second terminal end opposed to each other in the longitudinal direction of the main groove;
a semiconductor region formed in contact with a surface of the substrate in a region extending between the first terminal end and the second terminal end in the longitudinal direction of the main groove;
an electron supply region formed in contact with a surface of the semiconductor region on opposite sides of at least side surfaces of a surface of the main groove to generate a two-dimensional electron gas layer in the semiconductor region;
a first electrode formed in contact with the two-dimensional electron gas layer on the first terminal end; and
a second electrode formed in contact with the two-dimensional electron gas layer on the second terminal end and apart from the first electrode in the longitudinal direction of the main groove, wherein
the main groove has a depth greater than or equal to a total width of the main groove along a direction orthogonal to the longitudinal direction of the main groove.
