Abstract

Apparatuses, systems, and methods for determining local focus points (LFPs) on a sample are provided. In some embodiments, a controller including circuitry may be configured to cause a system to perform selecting a first plurality of resist pattern designs; performing a plurality of process simulations using the first plurality of resist pattern designs; identifying a hotspot that corresponds to a resist pattern design based on results of the performed process simulations; determining focus-related characteristics that correspond to a plurality of candidate resist patterns, wherein the plurality of candidate resist pattern designs is a subset of the first plurality of resist pattern designs and the subset is selected based on the identified hotspot; and determining locations of a plurality of LFPs based on the generated focus-related characteristics.
