    • An etch target layer and first to third mask layers are sequentially formed on a substrate in order to form a pattern structure. Hollow spacers are formed at each corner portion and center portion of first hexagons in a honeycomb shape where the hexagons are continuously arranged on the third mask layer. Second holes are formed between a first hole and the spacers in the spacer by forming a fourth mask pattern at an inner sidewall and an outer sidewall of the spacer. A third mask pattern and a second preliminary mask pattern are formed by etching the second and first mask layers. A second mask pattern including third and fourth holes having a diameter greater than the first and second holes by etching a sidewall of the second preliminary mask pattern. Further, a thin film pattern is formed by etching a first mask layer and the etch target layer using the second mask pattern. The pattern structure may have a target inner diameter.
    • 为了形成图案结构,在基板上依次形成蚀刻目标层和第一至第三掩模层。 在第一六边形的每个拐角部分和中心部分处形成空心间隔件,其中六边形连续地布置在第三掩模层上。 通过在间隔件的内侧壁和外侧壁处形成第四掩模图案,在第一孔和间隔物中的间隔物之间​​形成第二孔。 通过蚀刻第二和第一掩模层形成第三掩模图案和第二预备掩模图案。 第二掩模图案包括通过蚀刻第二预备掩模图案的侧壁而具有直径大于第一孔和第二孔的第三孔和第四孔。 此外,通过使用第二掩模图案蚀刻第一掩模层和蚀刻目标层来形成薄膜图案。 图案结构可以具有目标内径。

    • The present invention relates to a method for fabricating a gate insulating layer having low surface. As a subject matter of the present invention, the method for fabricating the gate insulating layer having the lower surface includes: a first step of producing a reactant by adding organic silane to silica particles distributed in a solvent to attach the organic silane to the surfaces of the silica particles; a second step of forming coatings by adding the organic silane to the reactant for networking between silicas having the surfaces with the organic silane attached thereto through the first step; and a third step of forming the gate insulating layer by coating the coatings formed through the second step on a substrate and performing heat treatment for the resultant at the temperature of 120°C to 400°C. The organic silane includes alkoxy group reacting with the silica particles and a side chain group participating in a reaction of forming the gate insulating layer of the silica. Accordingly, the gate insulating layer having low surface energy can be fabricated without an additional process such as a process of forming a self-assembled monolayer.
    • 本发明涉及一种具有低表面的栅极绝缘层的制造方法。 作为本发明的主题,制造具有下表面的栅极绝缘层的方法包括:第一步骤,通过将分散在溶剂中的二氧化硅颗粒加入有机硅烷来将有机硅烷附着到 二氧化硅颗粒; 通过将有机硅烷加入反应物中以形成涂层的第二步骤,用于通过第一步骤将具有与其连接的有机硅烷的表面的二氧化硅之间的联结; 以及第三步骤,通过在基板上涂覆通过第二步骤形成的涂层来形成栅极绝缘层,并在120℃至400℃的温度下对所得物进行热处理。 有机硅烷包括与二氧化硅颗粒反应的烷氧基和参与形成二氧化硅的栅极绝缘层的反应的侧链基团。 因此,可以制造具有低表面能的栅绝缘层,而无需附加工艺,例如形成自组装单层的工艺。
