Title (EN) PATTERN FORMING METHOD
(FR) PROCÉDÉ DE FORMATION DE MOTIF
(JA) パターン形成方法
Abstract:
(EN) This pattern forming method comprises: a step for applying a composition for underlayer film formation to a substrate; a step for applying a radiation sensitive composition for resist film formation directly or indirectly to an underlayer film which is formed by the step for applying a composition for underlayer film formation; a step for exposing a resist film to light, said resist film being formed by the step for applying a radiation sensitive composition for resist film formation; and a step for developing the resist film which has been exposed to light. The composition for underlayer film formation contains at least one of: a first component which produces a component having an acid group that is a sulfo group, a carboxy group, a phosphono group, a phosphoric acid group, a sulfuric acid group, a sulfone amide group, a sulfonyl imide group, a -CRF1RF2OH group or a combination of these groups by the action of heat; and a second component which is other than the first component and has one of the acid groups described above. The radiation sensitive composition for resist film formation contains 50% by mass or more of a metal-containing compound in terms of solid content.
(FR) La présente invention concerne un procédé de formation de motif comprenant: une étape consistant à appliquer une composition pour former un film de sous-couche sur un substrat; une étape consistant à appliquer une composition sensible aux rayonnements pour former un film de réserve directement ou indirectement sur un film de sous-couche qui est formé par l'étape consistant à appliquer une composition pour former un film de sous-couche; une étape consistant à exposer un film de réserve à une lumière, ledit film de réserve étant formé par l'étape consistant à appliquer une composition sensible aux rayonnements pour former un film de réserve; et une étape consistant à développer le film de réserve qui a été exposé à la lumière. La composition permettant de former un film de sous-couche contient au moins l'un des éléments suivants: un premier composant qui produit un composant contenant un groupe acide, tel qu'un groupe sulfo, un groupe carboxy, un groupe phosphono, un groupe acide phosphorique, un groupe acide sulfurique, un groupe sulfonamide, un groupe sulfonimide, un groupe -CRF1RF2OH ou une combinaison de ces groupes, sous l'effet de la chaleur; et un second composant qui est différent du premier composant et qui contient l'un des groupes acides décrits ci-dessus. La composition sensible aux rayonnements pour former un film de réserve contient au moins 50% en masse d'un composé contenant du métal en termes de teneur en solide.
