Methods of stacking semiconductor devices and methods of fabricating semiconductor device packages using the same

摘要

A stacked structure of semiconductor devices may include a plurality of stacked semiconductor devices, each having an upper surface and a lower surface and one or more via electrodes protruding from the upper surface to the lower surface. The via-electrodes may have upper parts (heads) protruding from the upper surface and lower parts (ends) protruding from the lower surface. The stacked semiconductor devices may be electrically connected to each other through the via-electrodes. A first adhesive film (e.g., patternable material) and a second adhesive film (e.g. puncturable material) may be formed between the stacked semiconductor devices. The stacked structure of semiconductor devices may be mounted on the upper surface of a printed circuit board (PCB) having a mount-specific adhesive film to form a semiconductor device package. The mounted stacked structure and the upper surface of the PCB may be further covered with a molding material.
