METHOD FOR SCRIBING BRITTLE MATERIAL SUBSTRATE

摘要

PURPOSE: A method for scribing a brittle material-based substrate is provided to form scribe lines according to inner segments by forming triggers, which are scribing points, on the surface of the substrate. CONSTITUTION: A method for scribing a brittle material-based substrate includes the following: Triggers(T1, T2) are formed on the surface of the brittle material-based substrate. A cutter wheel is rolled along scribe forming lines(L1, L2) from the position of the triggers to form scribe lines. A method for forming the triggers includes the following: The cutter wheel is prepared and is vertically dropped. The dropped cutter wheel is collided with the substrate.
