[Embodiment] Μ 1 '* 参蝴赖 ' ^ For the actual state of the turn Specifically, the figure 1 is a diagram of a laser tempering device for a laser beam. The laser retort shown in Fig. ' is set in the manufacturing process of a semiconductor device such as a reverse-staggered thin film transistor. 'Only in the opposite zone _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The laser light emitted by the group 2 is parallel to the whole axis, and is based on the recording microlens 5 The microlens array is irradiated onto the irradiated body 6. The laser vibrator is as described in Fig. 2 below, for example, a YAG laser is used as a light source, and the wavelength is 355 nm and the brain 201205650. The emitter is provided with a delay time between the two laser beams. The microlens array is arranged such that a plurality of microlenses 5 are disposed on the transparent substrate 4, and the laser light is collected on the irradiated body 6. The thin film transistor of the thin film transistor substrate is formed in a predetermined region. The transparent substrate 4 is disposed in parallel with the object 6 to be irradiated, and the microlens 5 is formed by an integral multiple of, for example, 2 or more of the arrangement pitch of the predetermined region of the transistor ( For example, 2) the irradiated body 6 of the present embodiment is, for example, a thin film transistor, and a predetermined region of the channel region of the a-Si is irradiated with laser light to form a polysilicon channel region. Above the microlens 5, a mask 3 for arranging the laser beam only for the pre-formed area of the microlens 5 is disposed, and the mask 3 is used to define the channel region by the illuminating body 6. As shown in Fig. 2, the laser oscillator i of the present embodiment includes a YAG laser light source u having a fundamental wave wavelength of 1064 nm, and a first wavelength crane H which converts the fundamental wave into two harmonics. 12. And the second wavelength conversion benefit 13 converted into a spectral wave of three times. The first wavelength converter π converts the fundamental wave from the laser light source u into the second frequency SHG) and outputs the fundamental wave and the second spectral wave. ', the third wave with a wavelength of 355nm and the second J = the local wave. In addition, in Fig. 2, the distance between the mirror 24 and the mirror 25 is 5 and the distance between the mirror 15 and the mirror 14 is not shown. For the sake of easy understanding, the actual physical size ratio is enlarged. Vertical and horizontal aspect ratio map. It is recognized that the third spectrum (wavelength: 355 lb) outputted by the reading ί ^ 长肉变 / 13 is irradiated onto the irradiated body 18 in which the amorphous frequency is formed by the package %% *2G. On the other hand, the basic output of the second wavelength converter 13 is L06^; ί14 ' 3 t. Further, the residual wave of the fundamental wave is 22. Next, the first optical system 19 of the fourth optical fundamental wave is constituted by the third and second 254. Therefore, the first optical system 22 constitutes a guide bow, and the second wavelength of the second wavelength converter 13 is outputted by the second 10 201205650 = (wavelength: 533 nm), and may also be delayed into the third universal wave (wavelength: % or not) The delay is used for the irradiation of the amorphous germanium film. The fundamental wave output by the secret 13 is partially reflected by the mirror 14, and is transmitted to the mirror 14. The amount of reflection and the amount of transmission are, for example, 50%. The f-wave is called a ρ-wave, and the fundamental wave of the transmission mirror 14 is the optical path of the third optical system 21 from the second Ϊ-wave, which is #1«访H: 13 via the mirrors 14, 15 And 16 from the lens 17 to reach the illuminated length if f length 'for example '3 m. For example, the object between the mirrors 14, 15 and the mirror 16 = about Um 'the basic wave output by the second wavelength class 13, The mirrors 14, p, and f can be used as the optical path of 3 m. Therefore, 50% of the fundamental waves are guided to the third optical system 21, and the third spectral wave is irradiated to the irradiated body via the second optical system. 18, the difference between the optical path lengths of the two (4) 3m, the optical path ^ = poor, 'the P wave of the fundamental wave is delayed relative to the third micro by about the amorphous germanium film. In addition, the mirror 14 is applied to the mirror 23, 24, 25 The s-wave in the fundamental wave of the radiation is guided to the fourth optical system 22 and is irradiated onto the object 18 to be irradiated. The fourth optical ray 22 is transmitted from the second wavelength converter 13 via the mirrors 14, 23, 24, and 25 And the mirror 17 reaches the irradiated body 18, and the optical path length is, for example, 6 m. For example, the physical distance between the mirrors 23, 24 and the mirror 25 is about 3 m, and the second wavelength converter 13 outputs the beauty mirror 23. 24 fold back, so the length of the optical path of 6m can be ensured. Therefore, 50% of the S wave in the base wave is guided to the fourth optical system 22, and the fundamental wave 50% of the P wave is guided to the third In the optical system 21, the optical path lengths of the two are different from each other, and the difference in the optical path length causes the s-wave of the fundamental wave to be delayed by about 10 ns with respect to the fundamental wave s, and then irradiated to the amorphous germanium film. The third harmonic, the p-wave, and the $wave' are radiated to the irradiated body 18 at a delay time of about 10 ns, and are disposed between the mirror 16 of the third optical system 21 and the lens 17. The shovel 26 for guiding the intensity of the laser light to the third optical system 21 and the fourth optical system 22, and the laser of the present embodiment configured as described above The fire action is explained. When the basic wave of the YAG laser is irradiated, the amorphous austenite film is irradiated, 201205650, the amorphous stone film is difficult to absorb, the YAG laser fundamental wave, the amorphous stone film cannot be melted, and the transmission is Amorphous stone film reaches the glass substrate of the substrate, causing damage to the glass substrate. Therefore, 'traditionally' YAG laser, the third harmonic (wavelength of 355 nm) is used to perform laser tempering. However, this implementation In the form of 'by the YAG laser light source 11, only the pulse output of the fundamental light (wavelength: 1064 nm) is performed once. Therefore, the laser light is converted into the second harmonic (SHG) by the first wavelength converter 12, and converted into the third ripple (THG) by the second wavelength converter 13 to which the second ripple and the base are input. Then, the 35th wave is irradiated to the object 18 by the lens 17, and the object 18 is locally melted. On the other hand, the chopping wave in the fundamental wave is delayed by the third optical system 21 including the mirrors 14, 15, and 16, for example, delayed by 10 ns with respect to the third spectral wave, and is irradiated to the irradiated body 18 again. The Ministry of Refining and Chemicals. Further, the s wave among the fundamental waves is delayed by the fourth optical system 22 including the mirrors 23, 24, and 25, for example, delayed by 1 ns with respect to the P wave, and then irradiated to the melted body 18 by melting. unit. In the third (a) diagram, after the third harmonic is irradiated, the p-wave of the fundamental wave is, for example, delayed by 1 〇 = re-irradiation, and the s-wave of the fundamental wave is delayed, for example, re-irradiated. Eight times, the third harmonic was irradiated because the third harmonic had a wavelength of 355 nm and was non-twisted. Suppose that when only the third harmonic is irradiated, the amorphous ruthenium film is irradiated by the '3 wave after about 50 邶, and then delayed by 1〇nS and then irradiated to the fundamental wave. The P wave is irradiated to the metal in the molten state. When it is different from the crystal, the wavelength of the local wave is recorded, and the second heat is absorbed. In addition, the p-wave of the fundamental wave is irradiated to the molten state ^Metal Si < moxibustion, when the s wave of the fundamental wave is delayed by 10 ns, the s ί* is sufficiently absorbed by the d-state i ifSi, and (4) the melting portion is given a large heat source. Applying "it, greater than the spectral wave", the intensity of the laser light is higher, however, the actual μ Γ ί basic wave, the energy is divided into 50%, the intensity is about - half of the p late time delay · Bureau === shot ^P wave and basic ΐΒ0 膜 间 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 第 第 第 第 第 第 第 第 第 第 第 第 第 第b) The heat shown. This gives a great heat to the amorphous stone film. When the third wave of YAQ·Laser is used, the heat is only 30% of the fundamental wave time. For example, 'yag laser In the case where the energy of the laser light of the fundamental wave of 10 mn 64 nm is 10, the amount of the 533 nm wavelength of the second harmonic is 5, and the energy of the 355 nm wavelength of the third spectrum is 3. Therefore, when the third harmonic is irradiated alone, the amount of heat imparted to the amorphous germanium film is small. Therefore, if heat is applied to the amorphous austenite film to perform tempering, the output of the YAG laser must be extremely large. Conventionally, the output loss is extremely large. _, phase, here, in the present embodiment, even if the third harmonic irradiation gives less heat to the amorphous germanium film, Before the solidification of the enthalpy, that is, after the irradiation of the third harmonic is 5 〇, the fundamental wave is sequentially irradiated in two steps, and the fundamental wave is given a large amount of heat to the melting portion. Thereby the YYAG laser light source η The emitted laser light energy can be efficiently used for the heating of the amorphous germanium film without waste, and the gamma ray laser light source u has the advantages of low cost and low running cost. The basic wave, because the energy is high, only 3 of the 5 waves and the fundamental wave, the fundamental wave is once irradiated as the high energy density. In contrast, in this embodiment, the fundamental wave is divided into the energy density. Two of the p-waves and the s-waves, which are the same as the harmonics of the third harmonic, and are delayed by a specific delay, and are then irradiated to the melting portion of the amorphous ray. Therefore, in the present embodiment, compared with the five soils. When two waves of the three spectral waves are used, the laser light of a certain intensity can be irradiated for a long time, and the amorphous germanium film absorbs the energy of the laser light with higher efficiency. The present invention is not limited to the above. The embodiment can be various deformations. The laser is limited to a yag laser and can be used. A kind of laser. Because the amorphous enamel film I is long and does not absorb the long-wavelength laser light, firstly, the short-wavelength laser light with good irradiation efficiency makes the amorphous resolving, after a certain amount of The molten metal of the metal state divides the characteristics of the present invention by dividing the long-wavelength and high-energy laser. Therefore, it is possible to use various laser light sources for performing the three-stage laser light. In addition, the laser light of the light energy, The above-described embodiment is divided into two, and may be divided into three or more, and may be set to be delayed, and the time may be sufficient. Further, the degree of division is not limited to 50% as described above. For example, Changed to 4G% and 6()% of the division 13 201205650 \ ratio. 1. In the above embodiment, the same light source of the YAG laser is used, and the L-th optical system 19 is used to delay the fundamental wave from the third harmonic. To perform the two-stage illumination, however, it is not limited thereto, and another laser source may be used to perform short-wavelength illumination and subsequent long-wavelength illumination. In this case, the timing of the first pulse is output, and the timing of the first pulse laser light of the wavelength is delayed by a specific delay time from the timing of outputting the second pulse of the short-wavelength light of the second oscillator, thereby controlling the timing of the pulse. can. On this day f, the second pulse of the laser light that is first irradiated should be a short wavelength of 550 nm or less. When it is 550 nm or less, the second pulsed laser light is absorbed by the amorphous germanium film. The amorphous germanium film can be sufficiently heated and melted. Therefore, the first pulse of the laser light after the energy is larger, the wavelength exceeds 550^. When the wavelength exceeds a long wavelength of 55 Å, it is difficult to absorb the amorphous film, and it does not melt, and a large energy can be imparted to the molten metal Si. Further, in the above-described embodiment, the first wavelength of the long-wavelength laser light is a fundamental wavelength, but the laser light of 533 nm of the second spectral wave may be used instead of the fundamental wavelength. The second harmonic of the 533 nm has an energy smaller than the fundamental wavelength. However, the second harmonic can be used depending on the total energy given to the amorphous film. Further, for example, the fourth harmonic, the fifth harmonic, or the like can also be used. Further, it is also known that LBO crystals (LiB3〇5) or KTP crystals (KTiOP〇4) are used as the second and third spectral generating elements. In addition, BBO Crystal ®-BaB2〇4) can also be used as the fourth harmonic generating element, which is well known. Further, the amorphous germanium film may be irradiated while sequentially delaying the third chopping, the second harmonic, and the fundamental wavelength of the laser light. [Industrial Applicability] According to the present invention, since a laser light source of a low-cost laser can be used to perform laser tempering of an amorphous germanium film, it is extremely useful for tempering technology using laser light.
