ABSTRACT:
According to an illustrative embodiment disclosed herein, a semiconductor structure comprising a first crystalline substrate and a second crystalline substrate is provided. The semiconductor structure is irradiated with a radiation. Both the first crystalline substrate and the second crystalline substrate are exposed to the radiation. At least one diffraction pattern of a crystal lattice of the first crystalline substrate and a crystal lattice of the second crystalline substrate is measured. A relative orientation of the crystal lattice of the first crystalline substrate and the crystal lattice of the second crystalline substrate is determined from the at least one diffraction pattern.
