    • A pattern forming method, includes: (i) a step of applying a resist composition whose solubility in a positive tone developer increases and solubility in a negative tone developer decreases upon irradiation with an actinic ray or radiation, the resist composition containing a resin capable of increasing a polarity by the action of an acid; (ii) an exposure step; (iii) a step of performing development by using a negative tone developer to form a resist pattern; and (iv) a step of causing a crosslinked layer-forming material to act on the resist pattern to crosslink the resin constituting the resist pattern and the crosslinked layer-forming material, thereby forming a crosslinked layer. According to the present invention, a method for forming a pattern having an effectively micro-dimensioned trench or hole pattern without generation of a scum is provided.
    • 图案形成方法包括:(i)施加其在正色调显影剂中的溶解度增加的抗蚀剂组合物和在负色调显影剂中的溶解度随着光化射线或辐射照射而降低的步骤,所述抗蚀剂组合物含有能够 通过酸的作用增加极性; (ii)曝光步骤; (iii)通过使用负色调剂进行显影以形成抗蚀剂图案的步骤; 和(iv)使交联层形成材料作用于抗蚀剂图案以交联构成抗蚀剂图案的树脂和交联层形成材料,从而形成交联层的步骤。 根据本发明,提供了一种形成具有有效的微尺寸沟槽或孔图案而不产生浮渣的图案的方法。

    • A method of forming patterns includes (a) coating a substrate with a resist composition for negative development to form a resist film having a receding contact angle of 70 degrees or above with respect to water, wherein the resist composition for negative development contains a resin capable of increasing the polarity by the action of an acid and becomes more soluble in a positive developer and less soluble in a negative developer upon irradiation with an actinic ray or radiation, (b) exposing the resist film via an immersion medium, and (c) performing development with a negative developer.
    • 一种形成图案的方法包括(a)用负显影用抗蚀剂组合物涂布基材以形成相对于水的后退接触角为70度或更高的抗蚀剂膜,其中用于负显影的抗蚀剂组合物含有能够 通过酸的作用增加极性,并且在通过光化射线或辐射照射时变得更可溶于正极显影剂并且在阴极显影剂中较少溶解,(b)通过浸渍介质曝光抗蚀剂膜,和(c) 用负面的开发人员进行开发。
