Abstract
Abstract The present invention relates to a semiconductor package which is loaded with a plurality of high-performance integrated circuits for high-performance systems such as super computers and large-sized computers. According to the invention, the packaging density of the semiconductor is doubled by stacking upper and lower members and forming substrates loaded with a plurality of chips in a multistep structure so that the size of computers can be minimized and heat emission efficiency can be improved by forming heat sinks in a fin-pin shape.
