Abstract:
1. A process of forming a multilayer stack comprising: obtaining a substrate, said substrate comprising devices having features with a critical dimension of about 70 nanometers; depositing a first thin film on said substrate with a first precursor comprising a first set of organic components, said first thin film having a thickness that is less than about 20.0% of said critical dimension; treating said first thin film to release said first set of organic components to leave a first set of pores; depositing a second thin film over said first thin film with a second precursor comprising a second set of organic compounds, said second thin film having a thickness that is less than about 20.0% of said critical dimension; treating said second thin film to release said second set of organic components to leave a second set of pores; and alternately depositing and treating further thin films to obtain a desired thickness for said multilayer stack.
