A method for improving a lithographic process for imaging a design layout onto a substrate using a lithographic projection apparatus comprising a patterning device, wherein the patterning device deforms from a first state to a second state, the method comprising: determining a deformation of the patterning device from the first state to the second state; determining a compensatory design layout from the design layout and the deformation; wherein the compensatory design layout is such that when the compensatory design layout is generated on the patterning device in the first state, the deformation of the patterning device deforms the compensatory design layout to the design layout. |
