Abstract:
In accordance with the present method and system for improving integrated circuit layout, a local process modification is calculated from simulated process response variables at a set of control points. Said modification values are incorporated into the layout constraints imposed by design rules and design intent to account for manufacturing friendliness. Solving the updated constraint equation with user specified objective function produces a new layout with increased manufacturability. The new layout may further contain data tags that enable optimal process correction to be performed on selected locations, leading to reduction in data size and mask complexity. Also in accordance with this invention, physical design tools are enhanced to read and process anisotropic design rules.

Claim (Index 24):
A method of producing a photolithographic design defining a plurality of layout objects in a photolithographic process, comprising:\n automatically laying out the plurality of layout objects in an initial photolithography design layout according to general design rules comprising at least one minimum distance rule and a design layout optimization; automatically detecting at least one critical area of the initial photolithography design layout based on an adverse effect of process latitude on the photolithographic process with respect to the at least one critical area; automatically selectively modifying the initial photolithography design layout, to define a modified photolithography design layout, the modified photolithography design layout having a local alteration of the at least one minimum distance rule dependent on a pattern of layout objects in a specific location of the original design layout to at least partially remedy the adverse effect of the process latitude on the photolithographic process with respect to the at least one critical area; and outputting the modified photolithography design layout.
