摘要： A laser annealing device (10) includes a laser oscillator (12), radiating a pulsed laser light beam of a preset period, and an illuminating optical system (15) for illuminating a pulsed laser light beam to an amorphous silicon film (1). The illuminating optical system (15) manages control for moving a laser spot so that a plural number of light pulses will be illuminated on the same location on the amorphous silicon film (1). The laser oscillator (12) radiates a laser light beam of a pulse generation period shorter than the reference period. The reference period is a time interval as from the radiation timing of illumination of a pulsed laser light beam on the surface of the film (1) until the timing of reversion of the substrate temperature raised due to the illumination of the laser light beam to the original substrate temperature.

摘要： The state of a polysilicon film formed by excimer laser annealing an amorphous silicon film is to be evaluated. When the amorphous silicon film is annealed to form a polysilicon film, linearity or periodicity presents itself in the spatial structure of the film surface of the polysilicon film formed depending on the energy applied to the amorphous silicon during annealing. This linearity or periodicity is processed as an image and represented numerically from the image by exploiting the linearity or periodicity. The state of the polysilicon film is checked based on the numerical results.

摘要： A method of growing a single crystal of KTiOPO.sub.4 which is a nonlinear optical material is disclosed. Growth of the single crystal of KTiOPO.sub.4 is carried out by melting a KTiOPO.sub.4 material with a flux to produce a melt, then contacting a seed crystal to the melt, and by slowly cooling at a saturation temperature or below. At this time, molar fractions of K.sub.2 O, P.sub.2 O.sub.5 and TiO.sub.2 contained in the melt fall within a region surrounded by six point in a K.sub.2 O-P.sub.2 O.sub.5 -TiO.sub.2 ternary phase diagram of A (K.sub.2 O:0.4150, P.sub.2 O.sub.5 :0.3906, TiO.sub.2 : 0.1944), B (K.sub.2 O:0.3750, P.sub.2 O.sub.5 : 0.3565, TiO.sub.2 : 0.2685), C (K.sub.2 O: 0.3750, P.sub.2 O.sub.5 : 0.3438, TiO.sub.2 : 0.2813), D (K.sub.2 O: 0.3850, P.sub.2 O.sub.5 : 0.3260, TiO.sub.2 : 0.2890), E (K.sub.2 O: 0.4000, P.sub.2 O.sub.5 : 0.3344, TiO.sub.2 : 0.2656), and F (K.sub.2 O: 0.4158, P.sub.2 O.sub.5 : 0.3744, TiO.sub.2 : 0.2098). In addition, K.sub.15 P.sub.13 O.sub.40 or the same composition produced by melting is used as the flux, and the proportion of a KTiOPO.sub.4 element in a composition of the melt is prescribed to 83.5 to 90.0 mol %. The seed crystal is set so that a C axis is in a direction perpendicular to a melt surface. Then, the seed crystal contacted to the melt is rotated and slowly cooled. Thus, a single crystal of KTiOPO.sub.4 of single domain at the end of growth can be produced.
