    摘要: A logical building block and method of using the building block to design a logic cell library for CMOS (Complementary Metal Oxide Silicon) ASICs (Application Specific Integrated Circuits) is disclosed. Different logic gates, built with the same building block as described in this invention, will have the same schematics of transistor connection and also the same physical layout so that they appear to be physically identical under optical or electron microscopy. An ASIC designed from a library of such logic cells is strongly resistant to a reverse engineering attempt.

    摘要: A technique for and structures for camouflaging an integrated circuit structure and strengthen its resistance to reverse engineering. A plurality of transistors are formed in a semiconductor substrate, at least some of the transistors being of the type having sidewall spacers with LDD regions formed under the sidewall spacers. Transistors are programmably interconnected with ambiguous interconnection features, the ambiguous interconnection features each comprising a channel formed in the semiconductor substrate with preferably the same dopant density as the LDD regions, with selected ones of the channels being formed of a conductivity type supporting electrical communication between interconnected active regions and with other selected ones of the channels being formed of a conductivity type inhibiting electrical communication but ambiguously appearing to a reverse engineer as supporting electrical communication.

    摘要: An integrated digital circuit is protected from reverse engineering by fabricating all transistors of like conductivity with a common size and geometric layout, providing a common layout for different logic cells, connecting doped circuit elements of like conductivity with electrically conductive doped implants in the substrate rather than metalized interconnections, and providing non-functional apparent interconnections that are interrupted by non-discernable channel stops so that all cells falsely appear to have a common interconnection scheme. The camouflage is enhanced by providing a uniform pattern of metal leads over the transistor array, with a uniform pattern of heavily doped implant taps from the transistors for connection to the leads; undesired tap-lead connections are blocked by channel stops.
