Patent ID: 7406870

Claim:
A semiconductor sensor comprising: a proof mass; a frame that is arranged around the proof mass; a beam that is arranged at a surface side of the frame and is configured to support the proof mass; a plurality of piezo-resistive elements arranged on the beam; an insulating film arranged on the surface side of said frame and beam supporting said proof mass of said semiconductor sensor, and said insulating film having through-holes corresponding to edge positions of the piezo-resistive elements; a plurality of metal wiring patterns and a plurality of pad electrodes arranged on the insulating film, said metal wiring patterns passing through said through-holes of said insulating film to electrically connect to the piezo-resistive elements; a cover plate that is fixed to the surface side of the frame via the insulating flim and is arranged to be spaced apart from the proof mass and the beam; and a cover plate fixing region for fixing the cover plate to the surface side of the frame, the cover plate fixing region including a formation region for the metal wiring patterns.
