SEMICONDUCTOR DEVICE HAVING FEATURES TO PREVENT REVERSE ENGINEERING.

摘要

It is desirable to design and manufacture electronic chips that are resistant to modern reverse engineering techniques. Disclosed is a method and device that allows for the design of chips that are difficult to reverse engineer using modern tear down techniques. The disclosed device uses devices having the same geometry but different voltage levels to create different logic devices. Alternatively, the disclosed uses devices having different geometries and the same operating characteristics. Also disclosed is a method of designing a chip using these devices.
