SCRIBING WHEEL, METHOD FOR MANUFACTURING THE SCRIBING WHEEL, AND SCRIBING METHOD

A scribing wheel for scribing a brittle material-made substrate. A disc-shaped scribing-wheel base material in use is so designed that a mid-portion of a disc periphery has the largest diameter. A diamond film is formed on the periphery by a CVD method. The periphery is ground in the middle so that...

Zusammenfassung:	A scribing wheel for scribing a brittle material-made substrate. A disc-shaped scribing-wheel base material in use is so designed that a mid-portion of a disc periphery has the largest diameter. A diamond film is formed on the periphery by a CVD method. The periphery is ground in the middle so that a plane including a circle defined by ridge line becomes perpendicular to the central axis of the scribing wheel.
