Publication number: 20110300692Abstract: The present invention relates to a method for dividing a semiconductor film formed on a substrate into plural regions by multiple laser beam irradiation using a sequence of at least two laser beam treatments affecting essentially a same area of said film. Except of a final laser beam treatment, the treatments of said sequence of at least two laser beam treatments are used for a conditioning of the treated film area which is to be removed. Said final laser beam treatment is applied to actually remove material in order to form a groove.
