Title: Pattern sensitive placement for manufacturability

This large gap results in strong refractive effects in lithography. Consequently, it is a huge challenge to reliably print layout features on wafers and the printing is more susceptible to lithographic process variations. Although resolution enhancement techniques can mitigate this manufacturability problem, their capabilities are overstretched by the continuous shrinking of VLSI feature size. On the other hand,the quality and robustness of lithography directly depend on layout patterns. Therefore, it becomes imperative to consider the manufacturability issue during layout design such that the burden of lithography process can be alleviated.Read More
