[Problem] A semiconductor device which achieves a fine pitch, a high throughput and a high connection reliability, especially in flip-chip mounting is provided. A method for manufacturing the semiconductor device and a circuit device using the semiconductor device are also provided.[Means for solving the problem] The semiconductor device has: an electrode; an insulating part having an opening on the electrode; a protruding part formed on the electrode; a protecting part which is formed at the periphery of the protruding part and electrically isolates the protruding part; and a bonding part which is formed on the protecting part by being spaced apart from the protruding part. An upper surface of the protruding part, an upper surface of the protecting part, and an upper surface of the bonding part form the same plane.
