Semiconductor Packages Having Package-On-Package Structures

摘要

A semiconductor package includes a lower package with a lower semiconductor chip on a lower package substrate, and an upper package with an upper semiconductor chip on an upper package substrate. The upper semiconductor chip has a plurality of chip pads and the upper package substrate has a plurality of substrate pads. The upper package is stacked on the lower package. The chip pads have a first pitch and the substrate pads have a second pitch greater than the first pitch. The upper package substrate has a plurality of connection lines that electrically connect the substrate pads to the chip pads.
