Claim Text:
1. A semiconductor device, comprising: an underlying layer including an insulator layer, and a metal layer provided on the insulator layer, the underlying layer including a first region and a second region; and a plurality of transistors arranged in a plane parallel to an upper surface of the underlying layer, the plurality of transistors including a first transistor provided on the first region and a second transistor provided on the second region, each of the first and second transistors including a semiconductor pillar provided on the metal layer, the semiconductor pillar providing a channel allowing a current to flow in a first direction intersecting the plane, a first channel of the first transistor having a first conductivity type and a first crystal orientation along the first direction; a second channel of the second transistor having the first conductivity type and a second crystal orientation along the first direction; and the second crystal orientation being different from the first crystal orientation.
