摘要: A semiconductor package and method for making the same are provided, wherein a lower chip having a plurality of conductive structures is bonded to an upper surface of a package substrate and a plurality of matrix walls are formed on the upper surface for surrounding the lower chip, such that an overcoat layer covering the matrix walls and the lower chip can be approximately removed after performing a grinding process to the lower chip to expose a plurality of conductive vias of the lower chip. The cleaning step for removing the residue of overcoat layer can be omitted, and the processing yield and the processing efficiency can be improved. The semiconductor package and the method is particularly suitable for stacking a large dimensional upper chip on a relatively small dimensional lower chip.
