    Abstract: PURPOSE: To suppress a generation of a surge current at the time of chucking operations. CONSTITUTION: In an electrostatic chuck comprising a dielectric 7 on a surface of a chuck electrode 6 and a power source 10 for a high voltage for applying a voltage to the chuck electrode 6, in order to attract and hold a wafer 11 placed on the dielectric 7 by an electrostatic force. A voltage control part 12 as voltage variable means for gradually changing an output voltage of the power source 10 for a high voltage is connected to the power source 10 for a high voltage. According to an instruction from the voltage control part 12, when the wafer 11 is attracted on the dielectric 7, an output voltage of the power source 10 for a high voltage is gradually increased, and further when the wafer 11 is detached from the dielectric 7, an output voltage of the power source 10 for a high voltage is gradually decreased.

    Abstract: PROBLEM TO BE SOLVED: To evaluate the state of a polysilicon film which is formed by excimer laser annealing an amorphous silicon film. SOLUTION: Related to the manufacturing process for an bottom-gate TFT, a polysilicon film is formed, and then its quality is decided. At formation of the polysilicon film by annealing an amorphous silicon film, linearity and periodicity appear in the spatial structure in the film surface of formed polysilicon film, according to the energy giving to the amorphous silicon at annealing. After the linearity and periodicity are image-processed, the linearity and periodicity of the image are made into numerical values utilizing an auto-correlating function. Then, the auto-correlating value of the surface image of polysilicon film in an S/D region as well as that on a gate electrode are acquired, and both numerical results is utilized to decide the quality of the polysilicon film.

    Abstract: PURPOSE:To provide a method for conveying a wafer which can accurately position the wafer without generating dusts. CONSTITUTION:The method for conveying a wafer comprises the steps of placing a wafer 1 removed from a wafer carrier 2 on a stage 4, then picking up the image of the wafer 1 by a CCD camera 6a, position-detecting the wafer 1 from the image in a rotating direction and a surface direction, and then moving a wafer conveyor 5 to a position of the wafer 1 based on a result of the detected position. Further, the wafer 1 may be positioned in its rotating direction by rotating the stage 4 based on a result of the detected position of the rotating direction.
