Summary: | 碩士 === 國立臺灣科技大學 === 化學工程系 === 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。
