Abstract
A method of generating data relative to the writing of a pattern by electronic radiation initially includes the provision of a pattern to be formed which form the work pattern with a single external envelope. The work pattern is broken down into a set of elementary outlines, each including a single external envelope. A set of insolation conditions is defined to model each elementary outline. An irradiated simulation pattern is calculated from the sets of insolation conditions associated with the sets of elementary outlines. The simulation pattern is compared with the pattern to be formed. If the simulation pattern is not representative of the pattern to be formed, shift vectors are calculated. The shift vectors are representative of different intervals existing between the two patterns. The external envelope of the pattern to be formed is modified from displacement vectors determined from the shift vectors. A new iteration is carried out.
