Method of making a multilayer electronic component with inter-layer conductor connection utilizing a conductive via forming ink

摘要

A multilayered electronic component created by a wet process, wherein a ceramic base is imprinted with an electrode and an interlayer via is formed on top of it by introducing a via pattern printed in ink that is incompatible with a layer of wet ceramic slurry coating placed on top of the electrode and the via pattern. The incompatibility leads to a physical-chemical reaction that removes ceramic material away from the top of the via pattern by diffusing ceramic materials contained in a colloidal suspension forming a via-through hole. After the wet ceramic slurry is dried, it surrounds the via-through hole and the imprinted via pattern. Then a new electrode layer is imprinted on top of the dried ceramic coating. The new electrode layer completes an electrically conductive path formed from the bottom-most electrode layer, to the via pattern, and then terminating at the new electrode layer on top.
