Stacked package for semiconductor device and fabrication method thereof, and apparatus for making the stacked package

摘要

A stacked semiconductor package with ultrahigh integration and a fabrication method thereof according to the present invention are provided to meet the requirements of a system device of being miniaturized and light-weighted and having high efficiency. Also, there is provide a jig for package aligning to fabricate the stacked semiconductor package. The semiconductor package according to the present invention is fabricated by mounting a second-type package including a molding portion and leads exposed at a lower surface of the molding portion of the second-type package on a first-type package including a molding portion and leads, each of being formed in a "J' shape, which are respectively extended out of both sides of the molding portion. Here, uppermost surfaces of the leads of the first-type package are welded by solder to bottom surfaces of the leads of the second-type package. The stacked semiconductor package according to the present invention has advantages in which work process is relatively short compared to the conventional art and also package fabrication costs are reduced.
