    Abstract: A method for determining a measurement recipe describing one or more measurement settings for measuring a parameter of interest from a substrate subject to an etch induced parameter error, the etch induced parameter error affecting measurement of the parameter of interest in a recipe dependent manner. The method include obtaining parameter of interest set-up data relating to measurements of at least one set-up substrate on which the parameter of interest has various first induced set values and etch induced parameter set-up data relating to measurements of at least one set-up substrate on which the etch induced parameter has various second induced set values. The recipe is determined so as to minimize the effect of the etch induced parameter on measurement of the parameter of interest.

    Abstract: A method for determining adjustment to a patterning process. The method includes obtaining a probability density function of a parameter related to a feature of a substrate subject to the patterning process based on measurements of the parameter, determining an asymmetry of the probability density function, and determining an adjustment to the patterning process based on the asymmetry of the probability density function of the parameter so as to reduce a probability of the feature having a parameter value that falls outside a range between threshold values of the parameter.
