Patent ID: 8713499

Claim:
A method of electron-beam lithography of networks of lines on a resin-coated substrate, said method being implemented by an electron-beam lithography equipment and a simulation equipment, the method comprising: selecting, at the simulation equipment, at least two opposite lines of the networks each opposite line having a critical line end in opposition to a critical line end of another opposite line; determining, at the simulation equipment, corrections to be applied to geometries of the critical line ends of said two opposite lines; determining, at the simulation equipment, a type of at least one contrast intensification structure chosen from among several patterns, said contrast intensification structure comprising at least two elements, at least one of which being located in-between said two opposite lines; calculating, at the simulation equipment, characteristic dimensions and a location of said contrast intensification structure in a gap between the critical line ends of said two opposite lines; generating, using the electron-beam lithography equipment, said contrast intensification structure; and placing, using the electron-beam lithography equipment, said contrast intensification structure in relation to the critical line ends of said two opposite lines as a function of determined parameters.
