Abstract:
A method for determining whether to order a mask structure using a processor may include acquiring a simulation result of an EUV pattern layout, determining a correlation parameter (CP), generating a predicted wafer process window, and determining the mask structure is suitable for ordering based on the CP and the predicted wafer process window. The processor may determine the CP based on a weighting value and a simulated depth of focus (DOF), a simulated energy latitude (EL), and simulated line-LER area and LER-width parameters in the simulation result. The CP may indicate a correlation between the simulation result of the EUV pattern layout and an actual wafer result of the EUV pattern layout. The predicted wafer process window may be generated using the processor based on the CP. The predicted wafer process window may indicate whether the actual wafer result of the EUV pattern layout will include a patterning defect.

Claim (Index 6):
The method of  claim 5 , wherein\n the generating the prediction of the FEM includes generating the predicted FEM margin map to include a first focus region, a second focus region surrounding the first focus region, a third focus region surrounding the second focus region, and a fourth focus region surrounding the third focus region, the generating the predicted wafer process window includes at least one of,\n in response to the EpPix value being greater than a first value and less than or equal to a second value, predicting the patterning defect not occur in the first focus region to the fourth focus region or the patterning defect occurs at the fourth focus region, \n in response to the EpPix value being greater than the second value and less than or equal to a third value, predicting the patterning defect occurring in at least one of the third focus region and the fourth focus region, \n in response to the EpPix value being greater than the third value and less than or equal to a fourth value, predicting the patterning defect occurring in at least one of the second focus region, the third focus region, and the fourth focus region, and \n in response to the EpPix value being greater than a fourth value, \n predicting the patterning defect occurs in at least one of the first focus region, the second focus region, the third focus region, and the fourth focus region.
