Patent ID: 8274165

Claim:
A semiconductor substrate comprising: a plurality of groove portions formed along scribe lines; insulating layers formed in the plurality of groove portions; a unit region surrounded by the plurality of groove portions; a wiring electrode including an extended terminal portion, the extended terminal portion of the wiring electrode extending from the unit region over an inside of one of the plurality of groove portions without passing across the one of the plurality of groove portions, an entirety of the extended terminal portion of the wiring electrode being flat without bending; and a surface insulating film which covers the insulating layers and has a connecting hole formed therein, the surface insulating film being formed without being divided into separate sections by the groove portions, wherein the wiring electrode is formed on the surface insulating film and is connectable via the connecting hole, the surface insulating film has an upper surface in contact with the wiring electrode and continuously extends across the plurality of groove portions, and the entire upper surface is flat.
