    • PROBLEM TO BE SOLVED: To provide a development processing method of preventing a pattern collapse, when removing a rinse liquid on a substrate, even if a resist pattern is made finer and the height is increased. SOLUTION: The development processing method includes processing liquid supply processes S14-S16 of supplying a processing liquid, where a hydrophobic agent for hydrophobizing the resist pattern is diluted by hydrofluoroether onto the substrate where the rinse liquid is supplied, after the resist pattern is developed; and processing liquid removal steps S18, S19 for removing the processing liquid from an area on the substrate to which the processing liquid has been supplied.

    • PROBLEM TO BE SOLVED: To provide a patterning process capable of efficiently insolubilizing a first positive resist pattern, thus achieving effective double patterning. SOLUTION: The patterning process includes steps of: applying a positive resist material onto a substrate to form a resist film, heat treating, exposing the resist film to high-energy radiation, heat treating, then developing with a developer to form a first resist pattern; applying a protective coating solution containing a silicon compound having at least one amino group and a hydrolyzable reactive group onto the first resist pattern, heating to cover the first resist pattern surface with a protective coating; and applying a second positive resist material on the substrate to form a second resist film, heat treating, exposing the second resist film to high-energy radiation, heat treating, and then developing the second resist film with a developer. For example, by double patterning of forming the second pattern in a space portion of the first pattern to reduce the pattern pitch to one half, the substrate can be processed by a single dry etching.

    • 要解决的问题:提供能够有效地使第一正性抗蚀剂图案不溶化的图案化工艺,从而实现有效的双重图案化。 图案化方法包括以下步骤:将正性抗蚀剂材料施加到基材上以形成抗蚀剂膜,热处理,将抗蚀剂膜暴露于高能量辐射,热处理,然后用显影剂显影以形成 第一抗蚀剂图案; 将含有至少一个氨基的硅化合物和可水解反应性基团的保护涂层溶液涂覆到第一抗蚀剂图案上,加热以用保护涂层覆盖第一抗蚀剂图案表面; 以及在所述基板上施加第二正性抗蚀剂材料以形成第二抗蚀剂膜,热处理,将所述第二抗蚀剂膜暴露于高能量辐射,热处理,然后用显影剂显影所述第二抗蚀剂膜。 例如,通过在第一图案的空间部分中形成第二图案的双重图案化以将图案间距减小到一半,可以通过单次干蚀刻来处理基板。 版权所有(C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a lithography method wherein a mask for generation of near-field radiation is not required to be accurately spaced from a resist-applied substrate or be brought into contact with a resist. SOLUTION: A lithographic method for a substrate provided with a resist layer and a further layer on the resist layer includes: providing a pattern in the further layer so that the resist layer may be exposed to radiation via a space defined by a distance between features of the pattern; and exposing the resist layer to radiation having a wavelength greater than the distance between features of the pattern defining the space, such that near-field radiation is generated which propagates into and exposes an area of the resist.

    • 要解决的问题:提供一种光刻方法,其中用于产生近场辐射的掩模不需要与抗蚀剂涂覆的基板准确地间隔开或与抗蚀剂接触。 解决方案:在抗蚀剂层上设置有抗蚀剂层和另外的层的基板的光刻方法包括:在另一层中提供图案,使得抗蚀剂层可以通过由距离限定的空间暴露于辐射 在模式的特征之间; 以及将抗蚀剂层暴露于具有大于限定空间的图案的特征之间的距离的波长的辐射,使得产生传播进入并暴露抗蚀剂的区域的近场辐射。 版权所有(C)2010,JPO&INPIT
