Title
(EN) METHOD FOR PRODUCING STRUCTURED CONDUCTIVE LAYERS
(FR) PROCÉDÉ DE PRODUCTION DE COUCHES CONDUCTRICES STRUCTURÉES
Abstract
(EN)
The invention relates to the production of a structured layer (2) having electrically conductive regions (2a), particularly the production of a structured transparent OLED electrode. The method starts with producing an initial layer (2') of an electrically conductive material, which is then rendered electrically insulating outside the intended conductive regions (2a). Thus the shape of the initial layer with for example a smooth surface (S) is preserved. Rendering the conductive material locally insulating can be achieved by irradiating and/or heating it locally (3 a) to change its chemical composition or crystalline structure. Moreover, dopants may locally (3b) be added by diffusion processes and/or by plasma printing.
(FR)
L'invention porte sur la production d'une couche structurée (2) comprenant des régions électriquement conductrices (2a), en particulier la production d'une électrode de dispositif électroluminescent organique (DELO) transparente structurée. Le procédé commence par la production d'une couche initiale (2') d'un matériau électriquement conducteur, qui est ensuite rendu électriquement isolant à l'extérieur des régions conductrices voulues (2a). La forme de la couche initiale, ayant par exemple une surface lisse (S), est donc préservée. Le matériau conducteur peut être rendu localement isolant par exposition à un rayonnement et/ou chauffage de celui-ci de façon locale (3a) pour changer sa composition chimique ou sa structure cristalline. En outre, des dopants peuvent être ajoutés localement (3b) par des processus de diffusion et/ou par impression plasma.
