Title (EN) METHOD FOR MANUFACTURING FLEXIBLE FUNCTIONAL SUBSTRATES
(FR) PROCEDE POUR LA REALISATION DE SUPPORTS FONCTIONNELS SOUPLES
Abstract:
(EN) The invention relates to a method for manufacturing a flexible substrate (310) including at least one functional element (308) which is micrometric or sub-micrometric in size, characterised in that it includes the following steps: depositing a sacrificial layer (302) onto a rigid so-called master substrate (304); forming said functional element (308) on said sacrificial layer (302); and transferring said functional element (308) onto a flexible substrate (310) by removing said sacrificial layer (302).
(FR) Procédé pour la réalisation d'un support souple (310) comprenant au moins un élément fonctionnel (308) de dimensions micrométriques ou sub- micrométriques, caractérisé en ce qu'il comprend les étapes suivantes : - dépôt d'une couche sacrificielle (302) sur un support rigide (304), dit maître, - réalisation dudit élément fonctionnel (308) sur ladite couche sacrificielle (302), - transfert dudit élément fonctionnel (308) sur un support souple (310) par élimination de ladite couche sacrificielle (302).
