SEMICONDUCTOR DEVICE AND MANUFACTURE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device called 'system module' obtained by stacking a plurality of semiconductor elements, which can reduce crosstalk noises induced between the semiconductor elements. SOLUTION: A first semiconductor element 1 having first electrode pads 2 and a first wiring layer 9 is superposed on a second semiconductor element 5 having second electrode pads 6 and a second wiring layer 10 to form a semiconductor device. In this semiconductor device a conductor layer 7 is formed on an insulating layer 8 in the second semiconductor element 5.
