摘要： Improved calibration of a resist model used in critical dimension (CD) calculation is disclosed. A dose function is obtained based on optical tool to be used form the resist on a wafer. The dose function indicates the amount of energy in a resist. The dose function is convolved with a convolution kernel to obtain a modified dose function. The convolution kernel has variable diffusion lengths in different directions. The convolution kernel may include multiple Gaussian kernels each having variable diffusion lengths in different directions. The modified dose function is converted into a CD value which is compared with a target value. If necessary, the diffusion lengths of the Gaussian kernels are adjusted based on the comparison result.

摘要： A process of obtaining short-range flare model parameters representing a short-range flare which degrades a contrast of an image generated by a lithography tool, is disclosed. Short-range flare is measured from the image to obtain measured short-range flare data. A simulation is performed based on short-range flare model parameters to obtain simulated short-range flare data. The simulated short-range flare data is compared with the measured short range flare data. It is determined whether the short-range flare model parameters used in the simulation is appropriate based on the comparison result. The short-range flare model parameters is optimized according to the measured short-range data and the simulated short-range flare data if the short-range flare model parameters used for the simulation is not appropriate.
