Patent ID: 8589827

Claim:
A non-transitory computer readable medium having instruction modules disposed thereon, the instruction modules, when executed by a processor, for instructing the processor to measure dimensional properties of a simulated photoresist profile, the instruction modules performing steps of: determining a number 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 the 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 specifying processes for fabricating integrated circuits based at least on the dimensional properties of the photoresist profile.
