Abstract: To improve reliability of a semiconductor device, in a flip-chip bonding step, a solder material that is attached to a tip end surface of a projecting electrode in advance and a solder material that is applied in advance over a terminal (bonding lead) are heated and thereby integrated and electrically connected to each other. The terminal includes a wide part (a first portion) with a first width W1 and a narrow part (a second portion) with a second width W2. When the solder material is heated, the thickness of the solder material arranged over the narrow part becomes smaller than the thickness of the solder material arranged in the wide part. Then, in the flip-chip bonding step, a projecting electrode is arranged over the narrow part and bonded onto the narrow part. Thus, the amount of protrusion of the solder material can be reduced.

Abstract: A memory card has a wiring board, four memory chips stacked on a main surface of the wiring board, and a controller chip and an interposer mounted on a surface of the memory chip of the uppermost layer. The memory chips are stacked on the surface of the wiring board so that their long sides are directed in the same direction as that of the long side of the wiring board. The memory chip of the lowermost layer is mounted on the wiring board in a dislocated manner by a predetermined distance in a direction toward a front end of the memory card so as not to overlap the pads of the wiring board. The three memory chips stacked on the memory chip of the lowermost layer are disposed so that their short sides on which pads are formed are located at the front end of the memory card.
