METHOD FOR MANUFACTURING A NANOPOROUS ULTRA-LOW DIELECTRIC THIN FILM INCLUDING A HIGH-TEMPERATURE OZONE TREATMENT AND NANOPOROUS ULTRA-LOW DIELECTRIC THIN FILM MANUFACTURED BY THE METHOD

摘要

Provided are a method for manufacturing a nanoporous ultra-low dielectric thin film including a high-temperature ozone treatment, and a nanoporous ultra-low dielectric thin film manufactured by the method. The method comprises: preparing a solution mixture by mixing a solution containing organic silicate matrix and a solution containing reactive porogen; forming a thin film by coating a substrate with the solution mixture; and performing thermal treatment on the thin film, and performing ozone treatment during the thermal treatment. A nanoporous ultra-low dielectric thin film manufactured by the method can have a permittivity of 2.3 or less and a mechanical strength of 10 GPa or more by improving size and distribution of pores in the thin film by virtue of high-temperature ozone treatment and optimized treatment temperature.
