Abstract: Un appareil de fabrication automatique traite un substrat (14) qui possède une surface décapée devant être remplie par la métallisation. Le système introduit le substrat automatiquement dans la chambre, puis le pose sur un dispositif de fixation, évacue les gaz de la chambre, effectue un décapage par plasma du substrat, et dépose sur celui-ci une couche adhésive puis des germes de nucléation après l'évacuation des gaz de la chambre. Un réacteur (11) situé à côté de la chambre porte un précurseur sublimable (10) du métal. Un système de transmission thermique (25, 52, 56) pour le réacteur (11) assure le refroidissement et le réchauffement sélectifs du réacteur (11) jusqu'à des températures supérieure et inféieure à la température de sublimation du précurseur, ledit réchauffement étant effectué pendant une période de sublimation prédéterminée commandée par un dispositif de temporisation. Le réacteur (11) est sélectivement relié à la chambre (24) afin de permettre le retour vers celle-ci des gaz sublimés. On chauffe le dispositif de fixation pour chauffer le substrat jusqu'à une température supérieure à la température de dissociation du précurseur, ce qui provoque un transfert du métal du précurseur au substrat et donc la nucléation de l'espèce métallique dans les emplacements des germes sur le substrat. Ensuite, on amène le système à une pression moins élevée après la fin de chaque période de sublimation prédéterminée, puis l'on enlève le substrat (14) du dispositif de fixation (15) et de la chambre (24).
