Lithography parametric yield estimation model to predict layout pattern distortions with a reduced set of lithography simulations

A lithography parametric yield estimation model is presented to evaluate the lithography distortion in a printed layout due to lithography hotspots. The aim of the proposed yield model is to provide a new metric that enables the possibility to objectively compare the lithography quality of different...

Sumario:A lithography parametric yield estimation model is presented to evaluate the lithography distortion in a printed layout due to lithography hotspots. The aim of the proposed yield model is to provide a new metric that enables the possibility to objectively compare the lithography quality of different layout design implementations. Moreover, we propose a pattern construct classifier to reduce the set of lithography simulations necessary to estimate the litho degradation. The application of the yield model is demonstrated for different layout configurations showing that a certain degree of layout regularity improves the parametric yield and increases the number of good dies per wafer.
