    Abstract: PROBLEM TO BE SOLVED: To allow manufacturing of a hybrid substrate, especially manufacturing of C-MOS structure to be simplified.
    SOLUTION: The method related to this invention forms primary and secondary active regions (1a, 1b, 1c and 14a, 14b) on a front face of a support material, wherein the active regions are respectively formed with primary and secondary single-crystal semiconductor materials having different, but preferably the same crystal structures. Further, the method gives a benefit that the front sides of the primary and secondary active regions (1a, 1b, 1c and 14a, 14b) are in the same plane. Especially, such a method forms the secondary active regions (14a and 14b) through a step to crystallize the secondary single-crystal semiconductor material from a pattern composed of the secondary polycrystal and/or amorphous semiconductor materials as well as an interface region between the pattern and the preselected primary active regions (1a and 1b). The support material is formed of lamination of a substrate (4) and an electric insulation layer (3), wherein the front side of the electric insulation layer (3) corresponds to the front side of the support material.
