Abstract
Multilayer capacitors, and/or circuit structures are formed from monolithic, sintered, ceramic matrices that have a plurality of dielectric or insulating ceramic strata or layers with intervening open-structured areas therebetween, by injecting into said areas molten metal to form internal electrodes or conductors, a penetrable barrier being provided if desired over the entrances to said areas before such injection.
Claims8
A sintered, unitary ceramic body comprising:
- a plurality of strata of a dense dielectric or insulating ceramic composition, said strata alternating with open-structured areas substantially parallel with said strata and extending to edges of said body, each of said open-structured areas containing at least some solid material and alternate ones of said open-structured areas extending to different edge regions of said body;
- and a penetrable barrier over each of said edge regions, said barriers permitting molten metal to be forced by pressure into said areas.
