ABSTRACT:
A semiconductor device provided with a semiconductor chip wherein an electrode pad is formed on a circuit formation surface, includes a first passivation film, which serves as an adhering layer; a second passivation film formed on the first passivation film, for protecting the semiconductor chip from external physical damage; a metal film formed so as to cover at least a first electrode-pad opening section of the first passivation film; and an external connection terminal to connect the electrode pad to an external equipment. A second electrode-pad opening section of the second passivation film is formed so as to expose the first electrode-pad opening section entirely. The second passivation film is formed so as not to be in direct contact with the electrode pad.
