摘要： The present invention provides a manufacturing method of a display device which can prevent the reduction of a size of a pseudo single-crystalline region having strip-like crystals in forming such a pseudo single-crystalline silicon region on a substrate. A step for forming pseudo single crystals having strip-like crystals on a preset region of a semiconductor film formed on a substrate includes a step for forming the pseudo single crystal by radiating an energy beam to a first region of the semiconductor film while moving a radiation position of the energy beam in a first direction, and a step for forming the pseudo single crystal by radiating the energy beam to a second region of the semiconductor film while moving a radiation position of the energy beam in a second direction opposite to the first direction. The first region and the second region set sizes thereof at a position where the radiation of the energy beam is finished smaller than sizes thereof at a position where the radiation of the energy beam is started. The second region includes a portion where the second region overlaps the first region and a portion where the second region does not overlap the first region.

摘要： A mechanism for always measuring the spatial intensity distribution of a laser beam and displacement of the optical axis of the laser beam is provided so that a measured signal is processed when the laser beam incident on a laser beam shaping optical element is out of a predetermined condition. The shape, diameter and incidence position of the laser beam incident on the laser beam shaping optical element are always kept in the predetermined condition by a spatial filter disposed at the position of a focal point of lenses forming a beam expander disposed in the optical axis, on the basis of a result of the signal processing.In this manner, silicon thin films uniform in crystallinity can be formed stably with a high yield on an insulating substrate which forms display panels of flat panel display devices.

摘要： When a laser bean temporally modulated in amplitude by a modulator is shaped into a long and narrow beam by a beam shaper, the scanning-direction size of the long and narrow beam shaped by the beam shaper is selected to be in a range of from 2 to 10 microns, preferably in a range of from 2 to 4 microns and the scanning speed of the beam is selected to be in a range of from 300 to 1000 mm/s, preferably in a range of from 500 to 1000 m/s. As a result, damage of the silicon thin film can be suppressed while energy utilizing efficiency of the laser beam can be improved. Accordingly, laterally grown crystals (belt-like crystals) improved in throughput can be obtained on a required region of a substrate scanned and irradiated with the laser beam.

摘要： A method of forming a semiconductor thin film includes a highly sensitive inspection method for detecting lateral crystals and a crystallizing method. In the crystallizing method, the time-based pulse width of a laser SXL is modulated and an approximate band-like crystal silicon film SPSI is formed in a desired region while scanning the substrate SUB1 bidirectionally in the X and −X directions. In the inspection method, an inspection beam PRO1 is irradiated to the substrate just after the laser SXL is turned off. A protrusion TOKI will be formed on the silicon film portion where the laser SXL is turned off if the state of the silicon film is that of a lateral crystal SPSI. The inspection beam PRO1 is scattered by the protrusion TOKI and observed by a detector. If the state of the silicon film is granular crystal GGSI or aggregated film AGSI, such a protrusion TOKI is not observed.
