Abstract: Disclosed herein is a lamination layer type semiconductor package, and more particularly, a lamination layer type semiconductor package capable of maintaining a thickness of a package on package structure at a minimum and minimizing a warpage defect by mounting two chips so as to correspond to each other. The lamination layer type semiconductor package includes: an upper package having an upper flip chip mounted on an upper substrate; a lower package having a lower flip chip mounted on a lower substrate and disposed so as to closely adhere the upper flip chip and the lower flip chip to each other; a heat dissipation adhesive member adhesively fixing the upper flip chip and the lower flip chip and dissipating heat generated from the upper flip chip and the lower flip chip; and a molding member molding between the upper substrate and the lower substrate.
