  • Patent number: 11195659
    Abstract: Improved termination features for multilayer electronic components are disclosed. Monolithic components are provided with plated terminations whereby the need for typical thick-film termination stripes is eliminated or greatly simplified. Such termination technology eliminates many typical termination problems and enables a higher number of terminations with finer pitch, which may be especially beneficial on smaller electronic components. The subject plated terminations are guided and anchored by exposed internal electrode tabs and additional anchor tab portions which may optionally extend to the cover layers of a multilayer component. Such anchor tabs may be positioned internally or externally relative to a chip structure to nucleate additional metallized plating material. External anchor tabs positioned on top and bottom sides of a monolithic structure can facilitate the formation of wrap-around plated terminations.

  • Patent number: 8826503
    Abstract: Methods of fabricating an array capacitor are disclosed, in which via structures of the array capacitor have increased uniformity in their transverse areas. One method involves perforating a capacitor body to form first holes extending from a first surface and partially through the capacitor body. The capacitor body may be further perforated to form second holes extending from a second opposed surface of the capacitor body. The second holes are to connect to the first holes to provide through holes extending across a thickness of the capacitor body. An appropriate conductive material may then be filled in the through holes to form via structures with increased uniformity in their transverse areas.
