    摘要: An amorphous silicon layer is deposited on a glass substrate via an underlayer insulating film, and further a light-emitting layer is inserted between the glass substrate and the underlayer insulating film in a partial region on the glass substrate. To measure light intensity distribution of laser light applied to the amorphous silicon layer, the laser light is applied to the light-emitting layer from the surface of a substrate to be treated. The light intensity distribution of the light emitted from the light-emitting layer is two-dimensionally imaged using an optical image pickup system from the back surface of the substrate to be treated, and measured using an image pickup device. The light intensity distribution of the laser light in the face to be treated is obtained from the light intensity distribution of the emission measured in this manner.

    摘要: A method for producing a thin film semiconductor device is described. In the method, a thin film layer of non-single-crystalline semiconductor, which is deposited on a base layer of glass, is processed to an island-shaped thin film layer at the time prior to the layer irradiation step. The laser irradiation to the thin film layer of non-single-crystalline semiconductor is carried out after forming an insulation film layer and a gate electrode over the island-shaped thin film layer, by using the gate electrode as the irradiation mask, whereby the center area of the island-shaped thin film layer masked by the gate electrode is crystallized, and simultaneously, the both side areas thereof which is not masked by the gate electrode are annealed. Next, a source electrode and a drain electrode is formed in the annealed areas. The implantation of impurity ion may be carried out either before or after the laser irradiation. By the above order of steps, it becomes possible to obtain a thin film semiconductor device which has small numbers of crystals and less variance of grain size of crystals for each unit of electric circuit, compared with a device produced by the conventional process. Further, the process makes it possible to be even the boundary surface between the crystallized layer and the insulation layer in a device.
