1. A method for defining a 3-D technology file structure, the method comprising the steps of:

  • providing a first circuit level identifier for a first circuit level in a 3-D integrated circuit;

    providing a second circuit level identifier for a second circuit level in said 3-D integrated circuit;

    providing a first 2-D technology file identifier for a 2-D technology file containing technology dependent information corresponding to said first circuit level;

    providing a second 2-D technology file identifier for a 2-D technology file containing technology dependent information corresponding to said second circuit level;

    creating a file structure configured for use in generating a 3-D integrated circuit layout, said file structure comprising said first circuit level identifier, said first 2-D technology file identifier, said second circuit level identifier and said second 2-D technology file identifier; and

    storing said file structure in a computer usable storage device.
