Abstract:
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.

Abstract:
The invention relates to an electric multi-layered component comprising ceramic dielectric layers which are stacked on top of each other between which component structures are arranged. The aim of the invention is to increase the mechanical stability, in particular soldering contact, on the component. As a result, an improved transversal form for transversal contacts is provided. Said transversal contacts have a transversal cross section which expands towards the top, at least partially, from the soldering contact to the lower side of the component.

A ceramic component (100) comprises a basic body (101) with two connecting contacts (102, 103) fitted thereon. The component (100) has a first longitudinally extended via electrode (104) and a second longitudinally extended via electrode (105), said electrodes each being coupled to one of the connecting contacts (102, 103).

Abstract:
Es wird ein Mehrschichtbauelement angegeben, das ein dielektrisches keramisches Material umfasst, welches sich mit einer Varistorkeramik zu einem erfindungsgemäßen monolithischen Mehrschichtbauelement co-sintern lässt. Das Mehrschichtbauelement umfasst daher eine Schicht einer Varistorkeramik und eine andere Schicht eines Dielektrikums. Beide Schichten können im Mehrschichtbauelement unmittelbar benachbart angeordnet sein. Im Mehrschichtbauelement sind auf oder zwischen den keramischen Schichten Metallisierungen angeordnet, die zu Leiterabschnitten und metallisierten Flächen strukturiert sind. Die Metallisierungen bilden zusammen mit den Keramikschichten neben einem Varistor zumindest ein weiteres Bauelement aus, welches ausgewählt ist aus zumindest einer der Bauelementfunktionen Kapazität, Widerstand und Induktivität.
