Semiconductor device comprising bump contacts

摘要

A semiconductor device including a semiconductor chip (10) which has an electrode and also has an active surface covered with an insulating layer (100). A rewiring circuit (120) is formed on the insulating layer (100) and is electrically connected to the electrode. An inner bump (140) is formed on a conductive pad (122) which is a part of the rewiring circuit (120). An insulating film (160) is attached to the rewiring circuit (120) and a surface of the insulating layer (100) at a peripheral portion of the rewiring circuit (120). The insulating film (160) has a through hole (180) into which the inner bump (140) is inserted. An outer bump (200) is superimposed on the inner bump (140) in the through hole (180) so as to project outwards away from the semiconductor chip (10).
