A stack type semiconductor package includes a lower semiconductor package including a lower package substrate and at least one lower semiconductor chip disposed on the lower package substrate; an upper semiconductor package including an upper package substrate larger than the lower package substrate and at least one upper semiconductor chip disposed on the upper package substrate; an inter-package connector connecting an upper surface of the lower package substrate to a lower surface of the upper package substrate; and a filler filling in between the lower package substrate and the upper package substrate while substantially surrounding the inter-package connector.

Stack type semiconductor package

A semiconductor device having a printed circuit board and a semiconductor chip. The printed circuit board includes a chip region, a plurality of first ball lands adjacent to the chip region, and at least one second ball land adjacent to the first ball lands. The semiconductor chip is mounted on the chip region. The first ball lands are arranged to have a first pitch. One of the first ball lands which is nearest to the second ball land, and the second ball land have a second pitch greater than the first pitch.
