Abstract:
The Ta 2O 5 isolation medium thin film was prepared with the anodic oxidation process. The morphology and composite of Ta 2O 5 film were characterized by scanning electron microscope (SEM), X-ray diffractions (XRD) and pectroscope (EDS), respectively. The results indicated Ta 2O 5 film was amorphous and had better surface. The electrical breakdown field intensity test system studied insulated performance of Ta-Ta 2O 5-Al composite films (MIM structure) in the FED component, indicated that the composite films had higher breakdown field intensity, which was 2.3 MV/cm. To analyze Ta-Ta 2O 5-Al composite films breakover mechanism, The schottky effect, F-N Effect were respectively regarded as the main mechanism.
