    摘要: There is provided an improvement on homogeneity of annealing performed utilizing radiation of a laser beam on a silicon film having a large area. In a configuration wherein a linear laser beam is applied to a surface to be irradiated, optimization is carried out on the width and number of cylindrical lenses forming homogenizers 103 and 104 for controlling the distribution of radiation energy density in the longitudinal direction of the linear beam. For example, the width of the cylindrical lenses forming the homogenizers 103 and 104 is set in the range from 0.1 mm to 5 mm, and the number of the lenses is chosen such that one lens is provided for every 5 mm-15 mm along the length of the linear laser beam in the longitudinal direction thereof. This makes it possible to improve homogeneity of the radiation energy density of the linear laser in the longitudinal direction thereof.

    摘要: A linear pulse laser beam to be applied to an illumination surface is so formed as to have, at the focus, an energy profile in the width direction which satisfies inequalities 0.5L1≦L2≦L1 and 0.5L1≦L3≦L1 where assuming that a maximum energy is 1, L1 is a beam width of two points having an energy of 0.95 and L1 +L2 +L3 is a beam width of two points having an energy of 0.70, L2 and L3 occupying two peripheral portions of the beam width. According to another aspect of the invention, a compound-eye-like fly-eye lens for expanding a pulse laser beam in a sectional manner is provided upstream of a cylindrical lens for converging the laser beam into a linear beam.

    摘要: In producing a semiconductor device by annealing with laser light irradiation, while a linear laser light is scanned in a direction perpendicular to a line, the annealing is performed for a semiconductor material. In this state, since an anneal effect in a beam lateral direction corresponding to a line direction is 2 times or more different than that in the scanning direction, a plurality of semiconductor elements are formed along a line direction in which the linear laser light is irradiated. Also, a line direction connecting the source and drain region of a thin film transistor is aligned to the line direction of the linear laser light.
