Abstract

A method includes loading the semiconductor structure on a stage; providing a detector disposed above the semiconductor structure and the stage; applying a voltage to the semiconductor structure; identifying a portion of the semiconductor structure at a temperature substantially greater than a predetermined threshold by the detector; rotating the stage and recording a rotation of the stage after identifying the portion of the semiconductor structure; and deriving a position of the portion of the semiconductor structure based upon the rotation of the stage.
