摘　　要：针对电容发展所面临的电容密度、绝缘强度和高频特性等方面问题,利用兼具横向、纵向电通量的叉指电极结构提出一种新型三维电容。电容测试及分析结果表明采用该设计结构能将电容最高击穿电压增大到40V,最高工作频率提升到10 GHz以上,电容值可调范围比平面电容扩大了2～3倍,有助于解决电容发展中面临的相关问题。Around the problems of capacitance density,insulation and RF property for the development of capacitors,a new type of three-dimensional（3D） capacitor was proposed.This 3D capacitor takes advantage of both horizontal,vertical electric flux between interdigital electrodes.According to the results of capacitors measurement and investigation,it show that with the help of 3D design,the applied capacitor voltage can be as high as 40 V,the working frequency is higher than 10 GHz,and the adjustable range of capacitance value is expanded 2-3 times compared with that of planar capacitors,those making it helpful for the development of modern capacitors.
