Abstract
L’invention porte sur un procédé de lithographie par auto-assemblage dirigé, ledit procédé comprenant une étape de dépôt d’un film de copolymère à blocs sur une couche neutre (20) vis-à-vis du copolymère à blocs, ledit film de copolymère à blocs étant destiné à être utilisé en tant que masque de lithographie, ledit procédé étant caractérisé en ce qu’il comprend les étapes suivantes : - déposer ladite couche neutre (20) sur une surface d’un substrat (10), ladite couche neutre (20) étant une couche de type carbonée ou fluoro-carbonée et déposée sur une épaisseur supérieure à 1,5 fois l’épaisseur du film (40) de copolymère à blocs, - réticuler ladite couche neutre,- déposer ledit film de copolymère à blocs, comprenant au moins un bloc silylé, sur ladite couche neutre réticulée (30), - soumettre l’empilement à une température d’assemblage afin de nano-structurer ledit copolymère à blocs,- retirer (G1) au moins un des nano-domaines (41,42) du film (40) de copolymère à blocs nano-structuré, afin de créer un motif destiné à être transféré par gravure(s) (G2, G3, G4) dans l’épaisseur du substrat (10).
