Title
(EN) SIMULATION-ASSISTED ALIGNMENT BETWEEN METROLOGY IMAGE AND DESIGN
(FR) ALIGNEMENT ASSISTÉ PAR SIMULATION ENTRE UNE IMAGE DE MÉTROLOGIE ET UNE CONCEPTION
Abstract
(EN)
A method including: simulating an image or characteristics thereof, using characteristics of a design layout and of a patterning process, determining deviations between the image or characteristics thereof and the design layout or characteristics thereof; aligning a metrology image obtained from a patterned substrate and the design layout based on the deviations, wherein the patterned substrate includes a pattern produced from the design layout using the patterning process; and determining a parameter of a patterned substrate from the metrology image aligned with the design layout.
(FR)
L'invention concerne un procédé consistant : à simuler une image ou des caractéristiques de celle-ci, à l'aide des caractéristiques d'une configuration de conception et d'un processus de formation de motif, à déterminer des écarts entre l'image ou les caractéristiques de celle-ci et la configuration de conception ou des caractéristiques de celle-ci ; à aligner une image de métrologie obtenue à partir d'un substrat à motif et la configuration de conception sur la base des écarts, le substrat à motif comprenant un motif produit à partir de la configuration de conception à l'aide du processus de formation de motif ; et à déterminer un paramètre d'un substrat à motif à partir de l'image de métrologie alignée avec la configuration de conception.
