Mechanical properties of Cu electroplated in supercritical CO2 emulsion evaluated by micro-compression test
Cu film and Cu micro-pillar where fabricated using supercritical CO2 emulsion (SCE). Cu electroplating with SCE (EPSCE) does not raise any impurity problems. Grain refinement was observed for the Cu film fabricated by EPSCE. Increase in strength was observed for the Cu film fabricated by EPSCE. The increase in strength is considered to come from grain refinement strengthening.
