Abstract
Life testing of M-Type dispenser cathodes was performed for 1000 hours to help quantify the performance enhancement due to different osmium-ruthenium (Os-Ru) thin film microstructures. Os-Ru film microstructures were selected based on their potential to inhibit tungsten/Os-Ru interdiffusion as identified in previous studies. The results show that the 10W substrate biased 150nm thick film yielded a very stable knee temperature throughout its life. However, the knee temperature was high in comparison to the standard Semicon film.
