Author Affiliations +
In this paper, we analyze advantages and disadvantages of various extraction-based techniques applied to colorless and colored double patterning layouts. Two techniques are presented: (1) an effective dielectric constant-based technique, which modifies the dielectric constants to obtain an equivalent capacitance change as would result from mask misalignment, and (2) an offset-based, less conservative technique, that proposes the use of custom corners. Experimental results illustrate the impact of double patterning on the parasitics, and allow us to compare these techniques.
