  • Patent number: 9491871
    Abstract: A carrier substrate includes a dielectric layer, a first circuit layer, an insulation layer, conductive blocks, and a first conductive structure. The dielectric layer has a first surface, a second surface, and blind vias. The first circuit layer is embedded in the first surface and the blind vias extend from the second surface to the first circuit layer. The insulation layer is disposed on the first surface and has a third surface, a fourth surface, and first openings exposing the first circuit layer. The conductive blocks fill the first openings and connect with the first circuit layer. A top surface of each of the conductive blocks is higher than the third surface of the insulation layer. The first conductive structure includes conductive vias filling the blind vias and a second circuit layer disposed on a portion of the second surface.

  • Patent number: 9460992
    Abstract: A through-holed interposer is provided, including a board body, a conductive gel formed in the board body, and a circuit redistribution structure disposed on the board body. The conductive gel has one end protruding from a surface of the board body, and an area of the protruded end of the conductive gel that is in contact with other structures (e.g., packaging substrates or circuit structures) is increased, thereby strengthening the bonding of the conductive gel and reliability of the interposer.

  • Patent number: 9111818
    Abstract: A packaging substrate is provided, including a substrate body having a plurality of conductive pads, an insulating protective layer formed on the substrate body for the conductive pads to be exposed therefrom, and a plurality of conductive pillars disposed on the conductive pads. Each of the conductive pillars has a bottom end and a top end narrower than the bottom end, thereby forming a cone-shaped structure that does not have a wing structure. Therefore, the distance between contact points is reduced and the demands for fine-pitch and multi-joints are satisfied.
