摘　　要：采用丝网印刷技术制备Ni-Cu-Zn铁氧体电感器薄膜,并对其性能进行了表征.XRD分析表明,铁氧体薄膜具有相同的晶格结构.研究结果表明,在引入了铁氧体薄膜后,电感器的电感量相对于空心电感器有30%左右的提高,品质因数依频率不同有所改善,共振频率有所降低.经400℃后处理的薄膜电感器在低频时性能最好,50 MHz时电感量提高了27%,品质因数提高了39%.Ni-Cu-Zn ferrite inductor film was fabricated by screen print technology,and its performances were in-vestigated.XRD results suggest that the as-prepared thin films exhibit the same crystalline structure.The results show that after introducing of ferrite film,the inductance increases by 30%,the quality factor is improved,and the resonance frequency decrease.Ferrite inductor thin films annealed at 400℃ exhibit an optimum performance with high quality at 50 MHz,inductance increased by 27%,the quality factor increased by 39%.
