Abstract: A method for fabricating an anti-fuse memory cell having a semiconductor structure with a minimized area. The method includes providing a reference pattern for the semiconductor structure, and applying a reverse OPC technique that includes inverting selected corners of the reference pattern. The reverse OPC technique uses photolithographic distortions to provide a resulting fabricated pattern that is intentionally distorted relative to the reference pattern. By inverting corners of a geometric reference pattern, the resulting distorted pattern will have an area that is reduced relative to the original reference pattern. This technique is advantageous for reducing the area of a selected region of a semiconductor structure which may otherwise not be possible through normal design parameters.
