Abstract:
1. A complementary transistor circuit, comprising: a first transistor that has a first channel region, a first drain, and a first source and that has a first-conductivity type; a second transistor that has a second-conductivity type that has a second channel region, a second drain, and a second source; the first transistor and the second transistor being formed using a plurality of single crystal grains; each of the plurality of single crystal grains covering one of a plurality of concave portions that are formed on an insulating substrate; the plurality of single crystal grains including a first single crystal grain that is formed on a first concave portion of the plurality of concave portions and a second single crystal grain that is formed on a second concave portion of the plurality of concave portions; a crystal grain boundary being located between the first single crystal and the second single crystal; a common electrode that is provided on the crystal grain boundary and that is coupled to one of the first drain and the first source and one of the second drain and the second source; at least one of the first drain and the first source being formed in the first single crystal grain; at least one of the second drain and the second source being formed in the second single crystal grain; one of the first drain and the first source being disposed between the crystal grain boundary and the first channel region; one of the second drain and the second source being disposed between the crystal grain boundary and the second channel region; and the first channel region not covering the first concave portion.
