Abstract
A method to easily determine parameters of a second process for manufacturing from parameters of a first process is provided. Metrics representative of differences between the first process and the second process are computed from a number of values of the parameters, which can be measured for the first process and the second process on a calibration layout, or which can be determined from pre-existing values for layouts or reference data for the first process and the second process by an interpolation/extrapolation procedure. A set of metrics are selected so that their combination gives a precise representation of the differences between the first process and the second process in all areas of a target design. Advantageously, the metrics are calculated as a product of convolution of the target design and a compound of a kernel function and a deformation function.
