    摘要: A method for forming a photoresist pattern involves the steps of: depositing a photoresist film on a substrate, the photoresist film containing an acid-generating agent capable of generating an acid upon exposure to light; overlaying an antireflective film over the photoresist film, the antireflective film containing a fluorine-based acidic compound; selectively exposing the photoresist; and developing the photoresist. The novel method is characterized in that the acid-generating agent and the fluorine-based acidic compound are selected so that the acid that the acid-generating agent generates in the photoresist film upon exposure to light has a higher acidity than the fluorine-based acidic compound in the antireflective film.

    摘要: A composition for formation of an antireflection film having an excellent etching resistant characteristic and ability to prevent reflection of short-wavelength light (absorption ability of short-wavelength light) as well as excellent time dependent stability, and an antireflection film in which the same is used, are provided. A composition for formation of an antireflection film including a siloxane compound having a light-absorbing group and a crosslinking group, the siloxane compound being blocked with a capping group, is provided. By thus blocking the siloxane compound with a capping group, time dependent stability can be improved without deteriorating etching resistance, and ability to prevent reflection.
