PATTERN FORMING METHOD, MULTI-LAYERED RESIST PATTERN, MULTI-LAYERED FILM FOR ORGANIC SOLVENT DEVELOPMENT, RESIST COMPOSITION, METHOD FOR MANUFACTURING ELECTRONIC DEVICE, AND ELECTRONIC DEVICE

摘要

There is provided a pattern forming method comprising: (i) a step of forming a first film on a substrate by using a first resin composition (I), (ii) a step of forming a second film on the first film by using a second resin composition (II) different from the resin composition (I), (iii) a step of exposing a multi-layered film having the first film and the second film, and (iv) a step of developing the first film and the second film in the exposed multi-layered film by using an organic solvent-containing developer to form a negative pattern.
