제목 Characterization of Electrical Reliability of Ultralow Dielectric Materials
초록 Nanoporous materials have gained much attention as ultralow dielectric materials because the continual increase in device and wiring densities in integrated circuits leads to the remarkable increase in RC delay. In order to decrease the dielectric constant, nanopores are introduced into dielectric materials, of which mechanical strength and electrical reliability were drastically reduced. Therefore, in order to characterize electrical reliability of the nanoporous SOGs, we applied voltage ramping dielectric breakdown test. The copolymer of methyl trimethoxysilane with bis-1,2-triethoxysilyl ethane was used as an organosilicate matrix and two types of reactive porogens were used. The first porogen was trimethoxysilyl cyclodextrin (TMSCD) which left a small amount of ash and another was trimethoxysilyl xylitol (TMSXT) which did not leave any residue. Comparative study with Cu and Ta electrodes showed that pores and carbon ash could act as electrical defects with the increasing porosity.
