Abstract:
1. A module board having embedded chips and components, comprising: a substrate having at least one large cavity and at least one small cavity, in which the large cavity passes through the substrate and at least one passive component is set in the small cavity; a heat-dissipation sheet set at the bottom of the substrate; a first adhesion layer which bonds the bottom of the substrate to the heat-dissipation sheet; at least one IC chip fixed in the large cavity of the substrate by a second adhesion layer, wherein the IC chip comprises a plurality of metal pads formed on the surface of the IC chip, wherein a plurality of electrical-test metal parts formed on the metal pads, respectively; a dielectric filling layer covering the entire surface of the substrate and filling all gaps at the surface of the substrate and in all of the cavities, wherein the dielectric filling layer has a plurality of micro vias to expose partial areas of the IC chip, the passive component and the substrate; and at least one wiring pattern layer formed on the dielectric filling layer to make the IC chip, the passive component and the substrate electrically connect.
