摘要： Apparatus for fabricating a display device includes a stage capable of mounting an insulating substrate of the display device and moving the insulating substrate, linear scales which detect a position or moving distance of the substrate, a laser oscillator which generates continuous-waves laser light, a modulator which turns ON/OFF the continuous-wave laser light, a beam forming optic which shapes the continuous-wave laser light passing through the modulator into a linear or rectangular form, an objective lens which projects the at least one of the laser light on the insulating substrate so as to irradiate the insulating substrate with the laser light. The controller counts signals generated by the linear scales for every movement of the stage for a given distance, causes the modulator to turn the generated continuous-wave laser light in an ON state at time when a position of the insulating substrate on which the laser light irradiation is to be started reaches an area on which the laser light is projected, and causes the modulator to turn the generated continuous-wave laser light in an OFF state at another time.

摘要： A laser beam is concentrated using an objective lens and radiated on a amorphous silicon film or polycrystalline silicon film having a grain size of one micron or less, the laser beam being processed from a continuous wave laser beam (1) to be pulsed using an EO modulator and to have arbitrary temporal energy change while pulsing ; (2) to have an arbitrary spatial energy distribution using a beam-homogenizer, filter having an arbitrary transmittance distribution, and rectangular slit; and (3) to eliminate coherency thereof using a high-speed rotating diffuser. In this manner, it is possible to realize a liquid crystal display device in which a driving circuit comprising a polycrystalline silicon film having substantially the same properties as a single crystal is incorporated in a TFT panel device.

摘要： The active layer (active region) of the thin-film transistor making up the driver circuit is obtained by reformation implemented by scanning the continuous-wave laser light, condensed into a linear form or a rectangle form extremely longer in the longitudinal direction than in the transverse direction, along a given direction crossing the longitudinal direction. This is made up of a poly silicon film containing crystal grains having no grain boundaries crossing the direction of current flow, that is, a band-like polycrystalline silicon film. As a result, it is possible to implement a display device having stable and high quality active elements outside the display region on the insulating substrate.

摘要： A method and apparatus for detecting defects are provided for detecting harmful defects or foreign matter with high sensitivity on an object to be inspected with a transparent film, such as an oxide film, by reducing noise due to a circuit pattern. The apparatus for detecting defects includes a stage part on which a substrate specimen is put and which is arbitrarily movable in each of the X-Y-Z-θ directions, an illumination system for irradiating the circuit pattern with light from an inclined direction, and an image-forming optical system for forming an image of an irradiated detection area on a detector from the upward and oblique directions. With this arrangement, diffracted light and scattered light caused on the circuit pattern through the illumination by the illumination system is collected. Furthermore, a spatial filter is provided on a Fourier transform surface for blocking the diffracted light from a linear part of the circuit pattern. The scattered and reflected light received by the detector from the specimen is converted into an electrical signal. The converted electrical signal of one chip is compared with that of the other adjacent chip. If these signals are not identical to each other, the foreign matter is determined to exist on the specimen in detection.
