摘要:
An excimer laser beam irradiation apparatus capable of processing a workpiece optimally with an excimer irradiation beam even when intensity distribution of the excimer laser beam undergone multiple reflections is non-uniform. A patterning mask has light-transmissive portions for allowing the excimer laser beam to pass through and a reflecting layer for reflecting it. A high reflectivity mirror disposed in opposition to the reflecting layer reflects the excimer laser beam reflected from the reflecting layer toward the patterning mask. An imaging lens images a pattern of the excimer laser beam transmitted through the patterning mask onto a workpiece for irradiation thereof. A workpiece moving mechanism and a mask moving mechanism move the workpiece and the mask moving mechanism, respectively. A control unit controls the workpiece moving mechanism and the mask moving mechanism such that the patterning mask and the workpiece are displaced along a same axis synchronously with each other in a scan moving direction which coincides with a direction in which the excimer laser beam shifts positionally while being reflected between the patterning mask and the reflecting means, for thereby allowing the workpiece to be scanned with the excimer laser beam. The workpiece can be processed uniformly and stably in accordance with a pattern of the patterning mask with high accuracy and reliability.

A setting device of a force feedback type has an operating unit commonly used to set a plurality of control items of an electronic device. To provide a different sensation to the operating unit depending on the control items, a force feedback pattern for an airflow rate setting is provided to a rotary knob, which is the operating unit, so that an operation of the rotary knob to rotate beyond an upper limit or a lower limit of an airflow rate range is restricted, and a force feedback pattern for the air outlet setting is provided to the rotary knob so that a rotational operation of the rotary knob is not restricted.
