    Abstract: A vapor chamber structure includes a first flexible substrate, a second flexible substrate, a spacer, a flexible sealing member, and a working fluid. The first flexible substrate includes a first organic material layer, a first copper foil layer, and a first capillary structure layer. The second flexible substrate includes a second organic material layer, a second copper foil layer, and a second capillary structure layer. The first copper foil layer, the first capillary structure layer, the spacer, the second copper foil layer, and the second capillary structure layer are retracted by a distance relative to the first and second organic material layers to form a space. The first and second organic material layers and the flexible sealing member define a sealed chamber. The working fluid is disposed in the sealed chamber and located among the first and second capillary structure layers and grooves of the spacer.

    Abstract: A circuit board structure includes a dielectric substrate, at least one embedded block, at least one electronic component, at least one first build-up circuit layer, at least one second build-up circuit layer, at least one conductive through hole, and a fine redistribution layer (RDL). The embedded block is fixed in a through cavity of the dielectric substrate. The electronic component is disposed in an opening of the embedded block. The first build-up circuit layer is disposed on a top surface of the dielectric substrate and electrically connected with the electronic component. The second build-up circuit layer is disposed on a bottom surface of the dielectric substrate and covers the embedded block. The conductive through hole is disposed in a via of the embedded block and electrically connects the first and the second build-up circuit layers. The fine RDL is disposed on and electrically connected to the first build-up circuit layer.
