Patent ID: 8258583

Claim:
An integrated circuit for making reverse engineering difficult comprising: a first electrically conductive doped channel having a first doping type between at least two first regions of the first channel having the first doping type; a first conductive layer over a portion of one of said first regions; and a second conductive layer over a portion of the other one of said first regions wherein said first conductive layer and said second conductive layer are spaced apart from one another; a second electrically conductive doped channel on the integrated circuit having a second doping type between at least two second regions of the second channel having the first doping type; a third conductive layer over a portion of one of said second regions; and a fourth conductive layer over a portion of the other of said second regions wherein said third conductive layer and said fourth conductive layer are spaced apart from one another; wherein edges of the first and second conductive layers are in a same relative location as edges of the third and fourth conductive layers.
