Outline of Final Research Achievements

We focused on the defect generation process in dielectric films (SiOC films) by low pressure plasma exposures to realize future highly reliable organic devices. We proposed a method quantifying the density of defects created by the plasma exposure, employing the capacitance-voltage measurement of the dielectric films. It was clarified that the nano-scaled indentation modulus as well as the effective dielectric constant strongly depend on the plasma process condition. The interaction between the localized defects and the microwave irradiated were investigated. The present findings provide a key guideline for novel organic device designs in the future.
