Title
(EN) METHOD FOR GLOBALLY ADJUSTING SPACER CRITICAL DIMENSION USING PHOTO-ACTIVE SELF-ASSEMBLED MONOLAYER
(FR) PROCÉDÉ DE RÉGLAGE GLOBAL DE DIMENSION CRITIQUE D'ESPACEUR À L'AIDE D'UNE MONOCOUCHE AUTO-ASSEMBLÉE PHOTO-ACTIVE
Abstract
(EN)
A method of processing a substrate includes: providing structures on a surface of a substrate; depositing a self-assembled monolayer (SAM) over the structures and the substrate, the SAM being reactive to a predetermined wavelength of radiation; determining a first pattern of radiation exposure, the first pattern of radiation exposure having a spatially variable radiation intensity across the surface of the substrate and the structures; exposing the SAM to radiation according to the first pattern of radiation exposure, the SAM being configured to react with the radiation; developing the SAM with a predetermined removal fluid to remove portions of the SAM that are not protected from the predetermined fluid; and depositing a spacer material on the substrate and the structures, the spacer material being deposited at varying thicknesses based on an amount of the SAM remaining on the surface of the substrate and the structures.
(FR)
L'invention concerne un procédé de traitement d'un substrat consistant à : disposer des structures sur une surface d'un substrat ; déposer une monocouche auto-assemblée (SAM) sur les structures et sur le substrat, la SAM réagissant à une longueur d'onde de rayonnement prédéfinie ; déterminer un premier motif d'exposition à un rayonnement, le premier motif d'exposition à un rayonnement ayant une intensité de rayonnement spatialement variable sur la surface du substrat et sur les structures ; exposer la SAM à un rayonnement conformément au premier motif d'exposition à un rayonnement, la SAM étant conçue pour réagir au rayonnement ; développer la SAM avec un fluide d'élimination prédéfini pour retirer des parties de la SAM qui ne sont pas protégées du fluide prédéfini ; et déposer un matériau d'espaceur sur le substrat et sur les structures, le matériau d'espaceur étant déposé à des épaisseurs qui varient sur la base d'une quantité de la SAM demeurant sur la surface du substrat et sur les structures.
