Abstract: Disclosed herein is a method for determining an image-metric of features on a substrate, the method comprising: obtaining a first image of a plurality of features on a substrate; obtaining one or more further images of a corresponding plurality of features on the substrate, wherein at least one of the one or more further images is of a different layer of the substrate than the first image; generating aligned versions of the first and one or more further images by performing an alignment process on the first and one or more further images; and calculating an image-metric in dependence on a comparison of the features in the aligned version of the first image and the corresponding features in the aligned versions of the one or more further images.

Abstract: Described herein are methods related to improving a simulation processes and solutions (e.g., retargeted patterns) associated with manufacturing of a chip. A method includes obtaining a plurality of dose-focus settings, and a reference distribution based on measured values of the characteristic of a printed pattern associated with each setting of the plurality of dose-focus settings. The method further includes, based on an adjustment model and the plurality of dose-focus settings, determining the probability density function (PDF) of the characteristic such that an error between the PDF and the reference distribution is reduced. The PDF can be a function of the adjustment model and variance associated with dose, the adjustment model being configured to change a proportion of non-linear dose sensitivity contribution to the PDF. A process window can be adjusted based on the determined PDF of the characteristic.

Abstract: Disclosed is a method for determining a mechanical property of a layer applied to a substrate. The method comprises obtaining input data comprising metrology data relating to said layer and layout data relating to a layout of a pattern to be applied in said layer. A first model or first model term is used to determine a global mechanical property related to said layer based on at least said input data; and at least one second model or at least one second model term is used to predict a mechanical property distribution or associated overlay map based on said first mechanical property and said layout data, the mechanical property distribution describing the mechanical property variation over said layer.
