SEMICONDUCTOR DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To promote reduction in the size and thickness of a system in package (SiP) configured by laminating a plurality of semiconductor chips on a wiring board.

SOLUTION: Bonding pads 13 of a logic chip 2 which is flip-flop mounted on a main surface of a wiring board 1 by a face-down method and lands 5a of the wiring board 1 are connected to barrier metal layers 14 and solder layers 15 which are formed on the bonding pads 13 through stud bumps 16s formed on respective lands 5a. Bonding pads 20 on a memory chip 3 mounted on the upper part of the logic chip 2 by a face-up method are connected to the lands 5a on the wiring board 1 through barrier metal layers 21 and Au wires 22 formed on respective bonding pads 20.
