Abstract: A semiconductor package may include a semiconductor chip including a chip pad, a redistribution structure including a redistribution insulation layer on the semiconductor chip and first redistribution patterns on a surface of the redistribution insulation layer, a passivation layer covering the first redistribution patterns, an UBM pattern on the passivation layer and extending into an opening of the passivation layer, a second redistribution pattern on the UBM pattern, conductive pillars on the second redistribution pattern, and a package connection terminal on the conductive pillars. The opening in the passivation layer may vertically overlap a portion of each of the first redistribution patterns. The second redistribution pattern may connect some of the first redistribution patterns to each other. Some of the conductive pillars may be connected to one another through the second redistribution pattern. The first redistribution patterns may be connected to the chip pad.

Abstract: A method of modeling a high speed channel in a semiconductor package, the high speed channel including a plurality of first connection wirings on an upper surface of a semiconductor substrate and a plurality of through electrodes penetrating the semiconductor substrate, includes: receiving design information of the high speed channel, dividing the design information into a first layout including the plurality of first connection wirings and a second layout including the plurality of through electrodes; performing a first modeling operation on the first layout using a first modeling scheme and a first modeling tool; performing a second modeling operation on the second layout using a second modeling scheme, a second modeling tool, and at least a portion of the first layout; and obtaining an integrated modeling result of an entirety of the high speed channel by combining results of the first and second modeling operations.

Abstract: A semiconductor package may comprise: a first passivation layer forming an electrical connection with one or more first bumps; a substrate layer including a second passivation layer and a silicon layer; a back-end-of-line (BEOL) layer formed on the substrate layer; and a third passivation layer formed on the BEOL layer forming an electrical connection with one or more second bumps, wherein the substrate layer includes a first signal TSV (Through Silicon Via) which transmits a first signal between the BEOL layer and a first lower pad, a second signal TSV which transmits a second signal between the BEOL layer and a second lower pad, and a ground TSV which is disposed between the first signal TSV and the second signal TSV and formed so that one end thereof is connected to the BEOL layer and the other end thereof floats.

Abstract: A stack package may include a first substrate package, a second substrate package, an interposer and at least one semiconductor chip. The first substrate package may include a plurality of first pads isolated from direct contact with each other by a first pitch. The second substrate package may be under the first substrate package. The second substrate package may include a plurality of second pads isolated from direct contact with each other by a second pitch. The second pitch may be different from the first pitch. The interposer may be above the first substrate package. The interposer may include a plurality of third pads isolated from direct contact with each other by a third pitch. The semiconductor chip may be arranged above the interposer.
