摘要： PROBLEM TO BE SOLVED: To obtain a laser annealing method and a laser annealer for annealing a semiconductor film by scanning it with a laser beam shaped into an elongated shape in which energy loss is reduced in a beam shaper for shaping the beam into an elongated shape, and the beam dimension and the scanning velocity are selected to attain lateral growth crystal stably with high throughput without being affected by variation in energy.
SOLUTION: A laser beam 3 subjected to time modulation by a modulator 7 is shaped into an elongated beam by means of a beam shaper 10. The beam shaper 10 sets the dimension in the scanning direction of the elongated beam in the range of 2-10 micron, more preferably in the range of 2-4 micron, the scanning velocity in the range of 300-1,000 mm/s, more preferably in the range of 500-1,000 mm/s. Consequently, energy efficiency is enhanced while retarding damage on the silicon thin film and a lateral growth crystal (stripe crystal) region is attained with high throughput by scanning a predetermined region on the substrate with a laser beam.

摘要： PROBLEM TO BE SOLVED: To reduce the number of alignment mark processing step during the formation of an active layer of a silicon film in a crystalline state, which is necessary for various circuits, on an insulating substrate that constitutes a flat display device, and thereby to achieve a high throughput and a low cost.
SOLUTION: An L-pattern 20 is formed on a photomask 17, and pattern matching is performed using the L-pattern 20 and a straight line or a nearly straight line (side) around a pseudo monocrystal region 11 on a substrate. At this time, the photomask 17 is driven relative to three axes XYθ together with the substrate so that the distance ΔX between the side 22 of the L-pattern 20, and the side 24 of the pseudo mnocrystal region 11 becomes equal to the distance ΔY between the side 23 of the L-pattern 20 and the side 25 of the pseudo monocrystal region 11, thus making the photomask and the substrate coincide with each other.

摘要： PROBLEM TO BE SOLVED: To selectively separate an upper electrode for every scanning line by laser ablation. SOLUTION: A YAG laser third harmonic with a laser wavelength of 355 nm is used. By setting film thickness of an interlayer insulation layer 15 to 100 nm and film thickness of a field insulation layer 14 to 140 nm, a spectral reflection spectrum has the minimum value near a wavelength of 355 nm, and a laser beam 20 is irradiated from an upper electrode 13 to a substrate 10. Although a part of the irradiated laser beam 20 is reflected by the upper electrode 13, its large part passes the field insulation layer 14 and the interlayer insulation layer 15 and is reflected by a lower electrode 11. The minimum value appears in the reflection spectrum by an interaction of these two reflected waves. In this case, the laser beam is absorbed mainly near an interface of the upper electrode 13/interlayer insulation film 15, the upper electrode 13 is ablated (melted and vaporized), and the upper electrode 13 is separated at this part. Thus, the upper electrode 13 is selectively cut without damaging the interlayer insulation film 15, the field insulation film 14 and the lower electrode 11, which serve as a foundation.

解决方案：使用激光波长为355nm的YAG激光器三次谐波。通过将层间绝缘层15的膜厚设定为100nm，将场绝缘层14的膜厚设定为140nm，光谱反射光谱的波长为355nm附近为最小值，激光束20为上部电极13到基板10.尽管照射的激光束20的一部分被上部电极13反射，但是其大部分通过场隔离层14和层间绝缘层15并被下部电极11反射。最小值通过这两个反射波的相互作用出现在反射光谱中。在这种情况下，激光束主要被吸收在上电极13 /层间绝缘膜15的界面附近，上电极13被烧蚀（熔化和蒸发），并且上电极13在该部分分离。因此，上部电极13被选择性地切割而不损坏作为基础的层间绝缘膜15，场绝缘膜14和下部电极11。版权所有（C）2007，JPO＆INPIT
