A virtual fabrication environment that enables 3D Design Rule Checks (DRCs) or Optical Rule Checks (ORCs) on 3D structural models of semiconductor devices to be performed is discussed. The virtual fabrication environment may perform 3D design rule checks, such as minimum line width, minimum space between features, and minimum contact area between adjacent materials, directly in 3D without making assumptions about the translation from 2D design data to a 3D structure effected by an integrated process flow for semiconductor devices.

A tool that allows three dimensional chip circuit designs to be checked subsequent to 3D design layer mirroring. The 3D chip design is converted to a corresponding 2D chip design by mirroring one or more design layers from the mirrored side of a 3D design and merging those design layers with unmirrored design layers from the unmirrored side of a 3D design. The converted circuit design can be processed by standard verification checks. The tool may also receive design layers corresponding to an integrated circuit that will pass through multiple semiconductor chips. Each design cell is examined to determine if it corresponds to a mirrored or unmirrored side of its respective semiconductor chip. If the respective design cell corresponds to the mirrored side, the design cell is mirrored. All mirrored cells are then merged with the unmirrored design cells in the correct order. The merged design is processed by standard verification checks. The tool also has the capability to create terminal metal abstracts for two adjoining chips. One of the abstracts is mirrored and then merged with the other for connectivity and alignment checking.
