Abrégé
(EN)
The invention relates to a deposition reactor including an in-feed part that defines an expansion space which is configured to lead reactants as a top to bottom flow from a plasma source (110) towards a reaction chamber, the expansion space widening towards the reaction chamber (335), and a lifting mechanism for loading at least one substrate (360) to the reaction chamber from the top side of the reaction chamber. The deposition reactor is configured to deposit material on said at least one substrate in the reaction chamber by sequential self-saturating surface reactions.
(FR)
L'invention concerne un réacteur de dépôt comprenant une partie d'alimentation qui définit un espace d'expansion lequel est configuré pour conduire des réactifs en tant qu'écoulement de haut en bas à partir d'une source de plasma (110) vers une chambre de réaction, l'espace d'expansion s'élargissant vers la chambre de réaction (335), et un mécanisme de levage pour charger au moins un substrat (360) dans la chambre de réaction à partir du côté supérieur de la chambre de réaction. Le réacteur de dépôt est configuré pour déposer une matière sur ledit ou lesdits substrats dans la chambre de réaction par des réactions de surface d'auto-saturation séquentielles.
