Composition for preparing substances having nano-pores

摘要

The present invention provides a composition for preparing substances having nano-pores, said composition comprising cyclodextrin derivative, thermostable organic or inorganic matrix precursor, and solvent for dissolving said two solid components. There is also provided an interlayer insulating film having evenly distributed nano-pores with a diameter less than 50 ANGSTROM , which is required for semiconductor devices.
