| Popis: | 90 Copper films were directly deposited on TaN surface by MOCVD。A highly conductive and pure copper film can be deposited conformally、continuously、and nonporously at 190℃for 9 min。 Instead SEM，the porousity and continuity of copper films can be determined by sheet resistance and reflectivity measurements，which provide noble methodologies for the end-point detection of seed layer deposition。 During the nucleation stage of copper films，the formation of more copper nuclei can produce copper films with smaller grains。Thus，we investigated the two-step growth methodology for the deposition of copper films：in the first step，the nucleation is done at 80℃ for 3 min then the temperature is raised to 190℃ and stayed there for 3 min；in the second step，the CVD is done at 190℃ for 3 min。 |
