Abstract: A method for fabricating an integrated semiconductor circuit having at least two different wiring forms realized in a same metallization plane includes drawing each of the different wiring forms on respectively different layer types. In this manner, the at least two different wiring forms can be individually and jointly analyzed.

Abstract: Lithographic fabrication of a microelectronic component is performed with the aid of OPC and a scatter bar structure. At least one scatter bar is applied on a mask in addition to a main structure for the purpose of a subsequent imaging of the main structure from the mask onto a substrate by exposure. At least one correction value for the OPC is selected in a particular manner in dependence upon a spacing between two parts of the main structure or a spacing between neighboring main structures and the presence of a scatter bar between the two parts of the main structure. The manner in which the correction value is defined is determined by so forming an auxiliary quantity for each scatter bar, that the largest auxiliary quantity that is set is less than the smallest spacing between the parts of the main structure, so that in a program for OPC the presence of a scatter bar between the two parts of the main structure is suggested.

Abstract: A method of fabricating a semiconductor device is outlined in FIG. 3. An ideal (or desired) pattern of a layer of the semiconductor device is designed (305). A first pass corrected pattern is then derived by correcting the ideal patterns for major effects, e.g., aerial image effects (315, 320). A second pass corrected pattern is then derived by correcting the first pass corrected patterns for remaining errors (304). The second pass corrected pattern can be used to build a photomask (345). The photomask can then be used to produce a semiconductor device, such a memory chip or logic chip (350).

In tis way, correction values for a rule-based OPC method are flexibly defined even in the presence of scatter bars.
