Title: Constant force mechanical scribers and methods for using same in semiconductor processing applications

Abstract: A scribing system comprising a mounting mechanism, stylus, and force generating mechanism is provided. The mounting mechanism is configured to rotate an elongated object in such a manner that the object is subjected to a bow effect wherein a middle portion of the object bends relative to the end portions of the object. The stylus is for scribing the object at a position x along the long dimension of the object while the mounting mechanism rotates the object. The force generating mechanism is connected to the stylus so that the stylus applies the same constant force to the elongated object regardless of the position x along the long dimension of the object that the stylus is positioned, while the mounting mechanism rotates the object and thereby subjects the object to the bow effect, thereby scribing the object.
