    摘要: Some embodiments of the present disclosure relate to a method to simulate patterning of a layout. The method comprises simulating formation of a layout pattern under a first lithography condition. The first lithography condition comprises a set of parameters, wherein a value of each parameter is defined by a corresponding process model. The method further comprises randomly varying the value of each parameter of the first lithography condition within a range of values defined by the corresponding process model of the parameter, to create a second lithography condition. Formation of a layout pattern is then re-simulated under the second lithography condition. Random variation of the value of each parameter is repeated to create additional lithography conditions. And, each lithography condition is re-simulated until the value of each parameter has been substantially varied across a range of its respective process model.
