Title: System and method for manufacturing thin film transistor, method for evaluating polysilicon, and polysilicon inspection device
Inventor: WADA HIROYUKI
IPC: H01L21/20
Filed: 2000-07-27
Abstract: PROBLEM TO BE SOLVED: To evaluate the state of a polysilicon film formed by annealing an amorphous silicon film by means of an excimer laser. SOLUTION: The manufacturing margin of the formed polysilicon film is found by evaluating the state of the film and the power of an excimer laser annealing device is set based on the manufacturing margin. When the polysilicon film is formed by annealing the amorphous silicon film, linearity or periodicity appears in the space structure on the surface of the formed polysilicon film according to the energy given to the amorphous silicon film at the time of annealing the film. After the linearity or periodicity is subjected to image processing, the linearity or periodicity is digitized from the obtained image by utilizing an autocorrelation function.  Then the difference between the autocorrelation value of the surface image of the polysilicon film on an SAD region and that of the surface image of the polysilicon film on a gate electrode is found and the manufacturing margin of the polysilicon film is calculated based on the difference.

Title: Exposure control method and scanning exposure device
Inventor: IKEMATSU TERUTSUGU
IPC: B41J2/47
Filed: 2000-07-31
Abstract: PROBLEM TO BE SOLVED: To simplify the assembly of a scanning exposure device which forms images of high accuracy and to reduce its manufacturing cost. SOLUTION: When the movement along a sub-scanning direction of an exposure heed is started, spacing correction data for one step component is read in and when the exposure head arrives at a corresponding movement position, a spacing regulation mechanism is activated in accordance with the spacing correction data to move the exposure head in a direction attaching and detaching to and from a rotary drum (steps 200 to 206). This operation is repeated at least within the exposure region of a printing plate, by which the spacing between the exposure head and the rotary drum is maintained constant and the out of focus of a light beam is prevented. As a result, even if the fabrication and assembly of parts are simplified, the formation of the images of high quality on the printing plate is made possible.
