Abstract: It is a problem to provide a semiconductor device production system using a laser crystallization method capable of preventing grain boundaries from forming in a TFT channel region and further preventing conspicuous lowering in TFT mobility due to grain boundaries, on-current decrease or off-current increase. An insulation film is formed on a substrate, and a semiconductor film is formed on the insulation film. Due to this, preferentially formed is a region in the semiconductor film to be concentratedly applied by stress during crystallization with laser light. Specifically, a stripe-formed or rectangular concavo-convex is formed on the semiconductor film. Continuous-oscillation laser light is irradiated along the striped concavo-convex or along a direction of a longer or shorter axis of rectangle.

Abstract: In commercial products to which a non-contact type or contact type ID label or ID tag is attached and ID cards, there is fear that, due to a difference between coefficients of thermal expansion between an antenna for communication and a resin provided around the antenna, stress is applied to the resin with the larger coefficient of thermal expansion to break the resin. This contributes to decrease in manufacturing yield, lifetime, and reliability of an ID label or the like. In an article such as an ID label, an ID tag, and an ID card according to the present invention, a filler is included in a filling layer provided around an antenna forming an ID label, an ID tag, and an ID card so that the difference in coefficient of thermal expansion between the antenna and the filling layer can be reduced. This makes it possible to ease generation of stress due to the difference in coefficient of thermal expansion and prevent peeling and cracks of the filling layer.

Abstract: To provide a TEG capable of early stage feedback of testing contents and a method of testing using the TEG. TFTs for TEG are manufactured on a different substrate than actual panel TFTs by using from among processes for manufacturing actual panel TFTs, processes that may easily lead to dispersion in the TFT characteristics, and the minimum number of processing steps necessary for TFT manufacture. The number of processing steps is fewer than the number for the actual panel, and therefore it is possible to complete the TFTs for TEG quicker than those of the actual panel, and it becomes possible to feed back an evaluation of the TEG TFT characteristics to the actual panel manufacturing process at an early stage. Time and costs associated with manufacture of the actual panel can therefore be suppressed.

Abstract: Position control of a crystal grain in accordance with an arrangement of a TFT is achieved, and at the same time, a processing speed during a crystallization process is increased. More specifically, there is provided a manufacturing method for a semiconductor device, in which crystal having a large grain size can be continuously formed through super lateral growth that is artificially controlled and substrate processing efficiency during a laser crystallization process can be increased. In the manufacturing method for a semiconductor device, instead of performing laser irradiation on an entire semiconductor film within a substrate surface, a marker as a reference for positioning is formed so as to crystallize at least an indispensable portion at minimum. Thus, a time period required for laser crystallization can be reduced to make it possible to increase a processing speed for a substrate.
