Classification: CPC H | IPC H

Claim 11:
12. A semiconductor package device, comprising:
a first chip;
a second chip configured to perform a transmission of at least one signal with the first chip via at least one channel;
a package substrate; and
an interposer comprising a semiconductor wiring substrate, a first surface and a second surface, wherein the first surface and the second surface are opposite to each other, the first chip and the second chip are connected to the first surface, and the package substrate is connected to the second surface;
wherein the semiconductor wiring substrate comprises at least one circuit layer and at least one dielectric layer, and a first circuit layer of the at least one circuit layer is electrically coupled between the second chip and the first chip to be a first channel of the at least one channel, so that the second chip and the first chip transmit a first signal of the at least one signal via the first circuit layer;
wherein the first circuit layer comprises a plurality of first signal traces and a plurality of first ground traces, wherein the first signal traces and the first ground traces are alternatively arranged on the first circuit layer, and one of the first signal traces is spaced at a first spacing from adjacent one of the first ground traces;
wherein a first dielectric layer of the at least one dielectric layer has a first thickness in an arrangement direction of the at least one circuit layer and the at least one dielectric layer, and the first spacing substantially ranges from 0.78 to 1.96 times the first thickness.
