A structural material includes a base material for forming a structure and an ion supplying source provided inside or on a surface of the base material, and the ion supplying source supplies at least one of a cation or an anion that constitutes a sparingly soluble salt having a water-solubility of no greater than a first value at a temperature of an environment where the base material is installed.

The present disclosure relates to a laminate substrate with sintered components. The disclosed laminate substrate includes a substrate body having an opening through the substrate body, a first foil layer, a sintered base component, and a sintered contact film. The first foil layer is formed underneath the substrate body, such that a first portion of the first foil layer fully covers the bottom of the opening. The sintered base component is formed within the opening and over the first portion of the first foil layer. Herein, the sintered base component has a dielectric constant between 10 and 500, or has a relative permeability greater than 5. The sintered contact film is formed over the sintered base component. The sintered base component is confined within the opening by the substrate body on sides, by the first foil layer on the bottom, and by the sintered contact film on the top.

The present disclosure relates to a process to integrate sintered components in a laminate substrate. The disclosed process starts with providing a precursor substrate, which includes a substrate body having an opening through the substrate body, and a first foil layer. Herein, the first foil layer is formed underneath the substrate body, so as to fully cover a bottom of the opening. Next, a sinterable base material is applied into the opening and over the first foil layer, and then sintered at a first sintering temperature to create a sintered base component. A sinterable contact material is applied over the sintered base component, and then sintered at a second sintering temperature to create a sintered contact film. The sintered base component is confined within the opening by the substrate body on sides, by the first foil layer on bottom, and by the sintered contact film on top.
