As the encryption level of chip design increases day by day, nowadays encryption technology is not only limited to the circuit and system level, but also implemented in the physical layout of chips. The topological structure you see under SEM(scanning electron microscope) is not having the normal logical function. We have followed physical encryption for decades, which gives us abundant experience in silicon physical obfuscation and camouflage analysis. Our team has created unique methods for massive analysis of special devices, which are competent for all special process analysis on current market. We are also able to complete scanning and analyzing of all special cells on a single chip at one time.
