Abstract

Abstract Translated from French Dispositif pour le dépôt d'une couche d'orientation d'une cellule à cristal liquide. Il comprend un support (12) linéaire plan apte à recevoir un ensemble de substrats (2) alignés suivant un axe d'alignement et une source (10) de pulvérisation cathodique disposée au-dessus dudit support et centrée sur ledit axe d'alignement, lesdits substrats et ladite source étant animés d'un mouvement relatif de translation suivant ledit axe d'alignement pendant le dépôt de la couche d'orientation, ledit mouvement faisant varier continûment l'angle d'incidence des particules déposées en chaque point d'un substrat dans un intervalle contenant l'incidence normale. Device for depositing an orientation layer of a liquid crystal cell. It comprises a flat linear support (12) capable of receiving a set of substrates (2) aligned along an alignment axis and a sputtering source (10) disposed above said support and centered on said alignment axis, said substrates and said source being driven in a relative translational movement along said alignment axis during the deposition of the orientation layer, said movement continuously varying the angle of incidence of the particles deposited at each point of substrate in an interval containing normal incidence.
