A negative resist composition is provided which comprises at least a constituent component which has a vinyl ether structure protected with an acetal in a molecule thereof. In the formation of negative resist patterns, an aqueous basic solution can be used without swelling. A process is also provided for forming a resist pattern, which comprises the steps of: applying a negative resist composition comprising at least a constituent component which has a vinyl ether structure protected with an acetal in a molecule thereof, on a to-be-treated substrate; selectively exposing the formed resist film to imaging radiation capable of provoking decomposition of a photo acid generator of the resist composition, and developing the exposed resist film with an aqueous basic solution.

The present invention provided an improvement to reduce an edge roughness during forming a small and fine pattern. Such an objective is to accomplish that after patterning a resist film, a coating film is formed on the resist film, so as to intermix the resist film material with the coating film material at the interface therebetween to reduce the edge roughness. There is provided a resist pattern-improving material, comprising: (a) a water-soluble or alkali-soluble composition, comprising: (i) a resin, and (ii) a crosslinking agent. Alternatively, The resist pattern-improving material, comprising: (a) a water-soluble or alkali-soluble composition, comprising: (i) a resin, and (ii) a nonionic surfactant. According to the present invention, a pattern is prepared in the step, comprising: (a) forming a resist pattern; and (b) coating the resist pattern-improving material on the surface of the resist pattern. According to the present invention, the resist pattern-improving material is mixed with the resist pattern at the interface therebetween. The resist pattern may be formed by irradiating a ArF excimar laser light or a laser light having a wavelength shorter than that of the ArF excimar laser light. The pattern of the resist pattern-improving material includes a base resin which does not substantially transmit the ArF excimar laser light.
