higher using both standard materials such as silicon and new GaAs, GaN, and others
in order to restore and then clone foreign analogs. The second possible function of
such systems is identification of hardware Trojans. This function is provided by a
specialized hardware and software complex, which ensures digitalization of chips
and wafers (in the modes of light and dark field, phase contrast, differential and interference contrast, polarization contrast, UV and confocal microscopy), processing,
stitching and printing of images, development of topology drawings, and circuit
recovery based on images.
