Abstract:
A method of creation a System On Package, comprising the steps of:providing a ceramic substrate having a first and a second surface; providing conductive plugs through said ceramic substrate in a direction that is perpendicular to the surface of said ceramic substrate, establishing points of electrical contact on said first and said second surface of said ceramic substrate; depositing a first layer of dielectric over the second surface of said ceramic substrate; then creating conductive vias through said first layer of dielectric that align with said points of electrical contact in the second surface of said ceramic substrate; or creating passive components on the surface of said first layer of dielectric, using thin film technology; or creating interconnect metal on the surface of said first layer of dielectric, said interconnect metal establishing connection with said conductive vias or said passive components created on the surface of said first layer of dielectric; then depositing at least one additional layer of dielectric over the surface of said first layer of dielectric; then creating conductive vias through said additional layer of dielectric that align with said passive components or said interconnect metal or said conductive vias of said first layer of dielectric; or creating passive components on the surface of said additional layer of dielectric, using thin film technology; or creating interconnect metal on the surface of said additional layer of dielectric, said interconnect metal establishing connection with said via openings or said passive components created on the surface of said additional layer of dielectric; depositing a last layer of dielectric over the surface of said at least one additional layer of dielectric; and establishing points of electrical contact in the surface of said last layer of dielectric by creating vias through said last layer of dielectric.
