    • PROBLEM TO BE SOLVED: To provide an electric multilayer component having a higher integration density that has significantly reduced parasitic capacitances and inductances on one hand, and allows especially simple and space-saving mounting on a print board on the other hand.
      SOLUTION: The electric multilayer component has a substrate constructed using stacked dielectric material layers, wherein multiple conductive electrode areas are arranged in the substrate at intervals between the dielectric layers, and electrodes are formed in the electrode areas. Furthermore, at least two solder balls (bumps) are arranged on the surface of the substrate for electrical contact of the component, each bump being connected in an electrically conductive way to at least one electrode via a through contact arranged in the substrate, so that first and second electrode stacks are formed, each of the electrode stacks contacting only one solder ball.

    • 要解决的问题:为了提供一方面具有显着降低的寄生电容和电感的较高集成密度的电气多层组件,另一方面在印刷电路板上安装尤其简单和节省空间。 解决方案:电气多层组件具有使用堆叠的电介质层构成的衬底,其中在电介质层之间间隔地在衬底中布置多个导电电极区域,并且在电极区域中形成电极。 此外,在基板的表面上设置至少两个焊球(凸块),用于部件的电接触,每个凸块通过布置在基板中的贯通触头以导电方式连接到至少一个电极,使得 形成第一和第二电极堆叠,每个电极堆叠仅接触一个焊球。 版权所有(C)2011,JPO&INPIT
