Abstract
A glass layer; a cavity penetrating a portion of the glass layer from an upper surface of the glass layer; an interconnect unit including at least a portion disposed in the cavity and including a polymer layer and a plurality of first through-vias each penetrating the polymer layer; and a plurality of second through-vias each penetrating the glass layer from a lower surface of the glass layer to a bottom surface of the cavity, wherein the plurality of first through-vias are connected to the plurality of second through-vias, respectively.
Claims22
A printed circuit board, comprising:
- a glass layer;
- a cavity penetrating a portion of the glass layer from an upper surface of the glass layer;
- an interconnect unit including at least a portion disposed in the cavity and including a polymer layer and a plurality of first through-vias each penetrating the polymer layer;
- and
- a plurality of second through-vias each penetrating the glass layer from a lower surface of the glass layer to a bottom surface of the cavity,
- wherein the plurality of first through-vias are connected to the plurality of second through-vias, respectively.
A printed circuit board, comprising:
- a glass core having a blind cavity;
- an interconnect unit having at least a portion disposed in the blind cavity;
- a plurality of second through-vias each penetrating the glass core in a region overlapping the blind cavity when the glass core is viewed from above;
- a plurality of third through-vias each penetrating the glass core in a region spaced apart from the blind cavity when the glass core is viewed from above;
- a first built-up structure disposed on an upper side of the glass core and including a plurality of first wiring layers;
- and
- a second built-up structure disposed on a lower side of the glass core and including a plurality of second wiring layers.
A printed circuit board, comprising:
- a glass layer having a top surface and a bottom surface;
- a cavity penetrating only a portion of the glass layer from the top surface thereof;
- an adhesive layer disposed on a bottom surface of the cavity;
- and
- a via extending from the bottom surface of the glass layer into the cavity and penetrating the bottom surface of the cavity and the adhesive layer.
