Abstract

L'objectif de l'invention est de créer un porte-substrats dans lequel les substrats peuvent être séparés facilement et sans frottement. Cet objectif est atteint grâce à un porte-substrats comprenant au moins deux éléments de maintien (8, 9) de substrats, sensiblement de même circonférence, destinés à maintenir des substrats en forme de disque placés entre ces deux éléments, au moins un des éléments de maintien (9) comportant une cavité (12) dans laquelle viennent se loger les substrats. Au moins un des éléments de maintien de substrats est pourvu d'au moins un aimant destiné à maintenir ensemble lesdits éléments de maintien. Par ailleurs, au moins un évidement (24) ménagé dans un premier des éléments de maintien de substrats permet de saisir par l'arrière un deuxième élément de maintien, tandis qu'au moins une ouverture (14) dans ce deuxième élément de maintien permet d'introduire un élément de retenue d'un dispositif de manipulation. L'invention concerne en outre un procédé, ainsi qu'un dispositif destiné à maintenir des substrats, ce dispositif comprenant au moins un premier et un deuxième élément de maintien de substrats, sensiblement de même circonférence, destinés à maintenir des substrats en forme de disque placés entre ces deux éléments, au moins un de ces éléments de maintien de substrats étant pourvu d'au moins un aimant destiné à maintenir ensemble lesdits éléments de maintien. Un dispositif de manipulation est utilisé pour séparer les éléments de maintien de substrats, ce dispositif comprenant au moins un élément de retenue servant à immobiliser le premier élément de maintien, ainsi qu'au moins un élément de préhension, mobile par rapport à l'élément de retenue, servant à saisir et déplacer le deuxième élément de maintien. L'élément de préhension peut être déplacé entre une position ouverte, libérant le deuxième élément de maintien, et une position fermée, dans laquelle le deuxième élément de maintien est saisi par l'arrière, ledit élément de préhension étant mobile dans une direction sensiblement perpendiculaire à un plan de jonction des éléments de maintien de substrats.
