Abstract:
A method of forming a pattern, which comprises the steps of:forming a mask material layer on a work film by coating a solution containing at least one kind of a network carbon polymer having a repeating unit represented by the following general formula (CP1), (CP2) or (CP4): wherein o, p and q are each independently a positive integer; forming a resist film on said mask material layer; forming a resist pattern by exposing said resist film to a patterning exposure light and by developing the exposed resist film; forming a mask material pattern by transferring said resist pattern to said mask material film; and forming a work film pattern by transferring said mask material pattern to said work film; wherein a complex index of refraction at a wavelength of said patterning exposure light of said mask material layer is in the range meeting the following relationships: 1.0&lE;n&lE;2.5; and 0.05&lE;k&lE;1.0.
