Abstract
A complementary MOS integrated circuit device has an MOS transistor of one conductivity type formed on a semiconductor substrate and an MOS transistor of another conductivity type opposite to the one conductivity type formed on the MOS transistor of one conductivity type through a separate layer. A dissimilar material whose nucleation density is sufficiently larger than that of the material of the separate layer and which is fine enough so that only a single nucleus of a semiconductor layer material grows is provided on the separate layer. The MOS transistor of the opposite conductivity type is formed in a monocrystalline semiconductor layer or substantial monocrystalline semiconductor layer provided by growing around the single nucleus formed on the hetero material.
