Patent ID: 7696630

Claim:
A semiconductor device comprising: a semiconductor chip including a semiconductor substrate and a high-frequency circuit block, the semiconductor substrate having a main surface, the main surface including a first area on which the high-frequency circuit block is disposed and a second area located around the first area; a plurality of electrode pads formed above the semiconductor substrate in the second area; posts formed above the semiconductor substrate in the second area, the posts being disposed between the high-frequency circuit block and the electrode pads and respectively connected to external terminals; and redistribution wiring layers which connect the electrode pads and the posts respectively, the redistribution wiring layers being formed above the semiconductor substrate in the second area, but not being formed above the semiconductor substrate in the first area, wherein the semiconductor chip further includes: a silicon oxide film formed on the main surface of the semiconductor substrate; aluminum wiring layers formed in and covered by the silicon oxide film, and connecting the high-frequency circuit block and the electrode pads; and a silicon nitride film formed on the silicon oxide film.
