Abstract

A method for transferring a fractured pattern decomposed into elementary shapes, onto a substrate by direct writing by a particle or photon beam, comprises a step of identifying at least one elementary shape of the fractured pattern, called removable elementary shape, whose removal induces modifications of the transferred pattern within a preset tolerance envelope; a step of removing the removable shape or shapes from the fractured pattern to obtain a modified fractured pattern; and an exposure step, comprising exposing the substrate to a plurality of shots of a shaped particle or photon beam, each shot corresponding to an elementary shape of the modified fractured pattern. A computer program product for carrying out such a method is provided.
