    Abstract: A method of exposing a wafer to exposure energy such as ultraviolet rays or X-rays through a mask to transfer a pattern of the mask onto the wafer, for example. The temperature of the mask and/or the wafer increases during the exposure operation by absorption of the exposure energy. During the wafer being exposed, the temperature of the mask and/or the wafer is detected. If the temperature is going to exceed the exposable temperature range determined on the basis of the line width of the pattern to be transferred, the exposure operation is interrupted. Then, the heat accumulated in the mask and/or the wafer is removed. Thereafter, the exposure operation is resumed. This is repeated until the predetermined or required amount of exposure is reached, for one shot. By this, the thermal expansion of the mask and the wafer during the exposure operation is prevented to assure the precision of the pattern transfer.

    Abstract: According to the invention, to make the reading operation of an eyesight handicapped person easy, the result of the image pickup of a camera unit to photoelectrically convert the character information is displayed by a pin pattern on a display. When the operator detects the character area from the display result, an area of an object for character recognition for the result of the image pickup is designated by an input unit and the execution of the character recognition is instructed. A processor recognizes the character with respect to the result of the image pickup of the designated area and displays the character so that it can be perceived in a tactile manner. Whether the result of the reading of the character is correct or not can be checked by a tactile perception. The recognition result of the character recognized can be generated by an audio output by an audio output unit.
