As a non-contact ID label, ID tag and the like being widespread, it is required to manufacture a considerable quantity of ID labels at quite a low cost. An ID label attached to a product is, for example, required to be manufactured at 1 to several yens each, or preferably less than one yen. Thus, such a structure and a process are demanded that an ID label can be manufactured in a large quantity at a low cost. A thin film integrated circuit device included in the ID label, the ID card, and the ID tag of the invention each includes a thin film active element such as a thin film transistor (TFT). Therefore, by peeling a substrate on which TFTs are formed for separating elements, the ID label and the like can be manufactured in a large quantity at a low cost.

The present invention provides a laser processing apparatus having a laser oscillator for outputting a pulsed laser beam; deflection unit for deflecting the pulsed laser beam to irradiate a object to be processed with the deflected pulsed laser beam; a mounting base on which the object is placed and which is movable in an axial direction or two-axial directions perpendicular to each other; and local shielding unit for controlling an atmosphere around the surface of the object to be processed which is irradiated with the laser beam. When a thin semiconductor film with a thickness of 1 μm or less is formed over the surface, minute convex portions are formed, which causes a problem that characteristics of TFTs vary among elements. Minute particles generated and adhered to a main surface of a substrate through a laser processing, which is difficult to remove in general surface cleaning, become preventable by the invention.
