METHODS OF FABRICATING POLYGON-SECTIONAL RODLIKE INGOT AND SUBSTRATE WITH ORIENTATION MARKER OR ROUNDED CORNERS, RODLIKE INGOT AND SUBSTRATE

摘要

The present invention discloses a method of forming a polygon-sectional rodlike ingot having an orientation marker or rounded corners, a rodlike ingot and a sheet substrate so formed. The method comprises: selecting one of sides of the polygon-sectional rodlike ingot that is parallel to an axial direction thereof as a first feature of a surface orientation marker; forming a minisize notch, which is parallel to an edge, in the one of sides selected as the first feature in the axial direction of the rodlike ingot, as a second feature of the orientation marker; and processing the rodlike ingot to form rounded corners. The sheet substrate is obtained by cutting the rodlike ingot.
