METHOD FOR ADJUSTING A TARGET FEATURE IN A MODEL OF A PATTERNING PROCESS BASED ON LOCAL ELECTRIC FIELDS

A method for determining a target feature in a model of a patterning process based on local electric fields estimated for the patterning process. The method includes obtaining a mask stack region of interest. The mask stack region of interest has one or more characteristics associated with propagati...

Zusammenfassung:	A method for determining a target feature in a model of a patterning process based on local electric fields estimated for the patterning process. The method includes obtaining a mask stack region of interest. The mask stack region of interest has one or more characteristics associated with propagation of electromagnetic waves through the mask stack region of interest. The mask stack region of interest includes the target feature. The method includes estimating a local electric field based on the one or more characteristics associated with the propagation of electromagnetic waves through the mask stack region of interest. The local electric field is estimated for a portion of the mask stack region of interest in proximity to the target feature. The method includes determining the target feature based on the estimated local electric field.
