Claim 0:
1. A method comprising:
inputting, into a resist deformation model, pattern information relating to a pattern to be formed in a patterning process, the model configured to simulate deformation of a portion of a resist, the portion comprising a boundary liquid layer located at a boundary between a developed or open region in the resist and a region of the resist at least partly surrounding the developed or open region, wherein the model is configured to determine a first deformation component of the boundary liquid layer caused by fluid flow of the boundary liquid layer and a second deformation component of the boundary liquid layer caused by the fluid flow of the boundary liquid layer; and
evaluating, by a hardware processor system, the resist deformation model with the inputted pattern information to determine a deformation of the pattern to be formed in the resist, wherein the deformation comprises a combination of the first deformation component and the second deformation component of the boundary liquid layer.
