  • Patent number: 8518530
    Abstract: The present invention relates to a production method for an ultra-low-dielectric-constant film, in which ratios are optimised in a mixed solution having a matrix consisting of a poly (alkyl silsesquioxane) copolymer and a porogen represented by Chemical formula 1, and in which this mixed solution is subjected to ultraviolet curing during a heat treatment. The ultra-low-dieletric-constant film of the present invention can be used as an intermediate insulating film for next generation semiconductors instead of the SiO2 dielectric films currently used, since pores of from 1 to 3 nm are uniformly distributed at from 10 to 30% and a very high degree of mechanical elasticity of from 10.5 to 19 GPa is achieved at a low dielectric constant from 2.12 to 2.4.
