Abstract
A method of manufacturing a semiconductor device, includes providing a mark above a main surface on a semiconductor substrate, separating the semiconductor substrate into a plurality of semiconductor elements by cutting the semiconductor substrate, determining a reference semiconductor element on the basis of a coordinate data indicating coordinates of the mark and coordinates of all of the semiconductor elements on the semiconductor substrate, and picking-out the semiconductor elements on the basis of the coordinate data using a pick-out apparatus. The providing operation includes forming a protective coat onto the main surface of the semiconductor substrate, irradiating a point on the main surface of the semiconductor substrate with a laser beam through the protective coat, and eliminating the protective coat from the main surface of the semiconductor substrate.
