METHOD FOR SEPARATING AND TRANSFERRING IC CHIPS

A method for separating a multiple number of semiconductor devices or semiconductor integrated circuits from a wafer on which the multiple number of semiconductor devices or semiconductor integrated circuits are formed is provided. The method includes separating each of the semiconductor devices or semiconductor integrated circuits. Each of the separated semiconductor devices or semiconductor integrated circuits is non-rectangular shaped, and the step of separating each of the semiconductor devices or semiconductor integrated circuits is performed by dry etching. A test device is formed on an area of a groove width required for separating the semiconductor devices or semiconductor integrated circuits, and the semiconductor devices or semiconductor integrated circuits are separated without a waste of space except for the area of the groove width required for separating the semiconductor devices or semiconductor integrated circuits, with the test device being separated from the semiconductor devices or semiconductor integrated circuits.
