PROCESS FOR MAKING LAMINATE SUBSTRATE WITH SINTERED COMPONENTS
20200147695 · 2020-05-14 ·

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.
