Abstract:
1. A method comprising: obtaining a ceramic block comprising a metalized through-hole and a dielectric material, wherein the metalized through-hole extends entirely through the ceramic block; applying a photodefinable ink made of a photosensitive metal ink containing metal particles and photosensitive organic compounds to the dielectric material to form a photodefinable layer on the dielectric material; performing a first drying of the photodefinable layer; exposing a portion of the photodefinable layer through a predefined mask resulting in an organic-metal particles containing-composition pattern on the dielectric material of the ceramic block, wherein the organic-metal particles containing-composition pattern is positioned on the dielectric material of the ceramic block in contact with the metalized through-hole to provide inter-cavity coupling with another organic-metal particles containing-composition pattern positioned on second dielectric material of a second ceramic block having a second metalized through-hole; applying a developer solution to an unexposed portion of the photodefinable layer to dissolve the unexposed portion of the photodefinable layer on the dielectric material; rinsing the organic-metal particles containing-composition pattern on the dielectric material; and performing a second drying of the ceramic block having the organic-metal particles containing-composition pattern on the dielectric material.
