Abstract:
A semiconductor package includes a substrate, a semiconductor chip located on a top surface of the substrate, signal lines formed on the top surface of the substrate and configured to allow different types of signals to input/output thereto/therefrom, a ground line unit formed on the top surface of the substrate and configured to divide the signal lines into signal lines to/from which the same types of signals are input/output to be isolated from one another, barrier walls configured to contact the ground line unit, and a heat dissipation unit disposed on the semiconductor chip, wherein the ground line unit includes diagonal ground lines located in diagonal directions of the substrate about the semiconductor chip, and the heat dissipation unit includes a thermal interface material (TIM) located on a top surface of the semiconductor chip, and a heat dissipation plate configured to cover the TIM and the substrate.
Abstract:
A package stack structure may an upper package include an upper package substrate having a first edge and a second edge opposite to the first edge. The upper package substrate has a first region arranged near the first edge and a second region arranged near the second edge. A first upper semiconductor device is mounted on the upper package substrate. The package stack structure may also include a lower package having a lower package substrate and a lower semiconductor device. The lower package is connected to the upper package through a plurality of inter-package connectors. The plurality of the inter-package connectors may include first inter-package connectors configured to transmit data signals; second inter-package connectors configured to transmit address/control signals; third inter-package connectors configured to provide a supply voltage for an address/control circuit; and fourth inter-package connectors configured to provide a supply voltage for a data circuit.
