Abstract:
A semiconductor chip having a bonding face to be mounted onto a mother board,wherein a low elastic modulus resin layer is provided in contact directly with said bonding face of said semiconductor chip without intervening any interposer to form a chip size package, and wherein said low elastic modulus resin layer has both a sufficiently low elastic modulus and a sufficiently large thickness for allowing realization of a stress caused due to a difference in thermal expansion coefficient between said semiconductor chip and said mother board and wherein said low elastic modulus resin layer has holes positioned over conductive pads on said bonding face of said semiconductor chip, and conductive patterns of a build-up type extend at least in said holes and in direct contact with said conductive pads and also extend over said low elastic modulus resin layer and directly contact with externally connective contacts over said low elastic modulus resin layer.
