Claim:
1. A processor based method for measuring dimensional properties of a simulated photoresist profile, the method comprising steps of: determining a number of acid generators and quenchers within a virtual photoresist volume; determining a number of photons absorbed by the virtual photoresist volume, determining a number of the acid generators converted to acid within the virtual photoresist volume; determining a number of acid and quencher reactions within the virtual photoresist volume; calculating a development of the virtual photoresist volume; producing with a processor a three-dimensional simulated scanning electron microscope image of the simulated photoresist profile created by the development of the virtual photoresist volume; measuring the dimensional properties of the simulated photoresist profile; and fabricating integrated circuits based on the dimensional properties of the photoresist profile.
