摘要： An electron microscope stage mechanism capable of performing high-accuracy positioning while limiting vibration and drift. An ultrasonic motor is used in a stage drive mechanism, and a fixing mechanism capable of increasing stop stiffness is combined integrally with the motor. That is, a structure in which a piezoelectric actuator of the fixing mechanism is mounted in a pre-load mechanism together with the ultrasonic motor is used. When the stage is fixed by the fixing mechanism after acceleration, deceleration and positioning of the stage performed by the drive mechanism, the piezoelectric actuators positioned on opposite sides of the stage are extended to press the stage.

摘要： A wafer transport method includes the steps of preparing a semiconductor process equipment having a transport chamber and a process chamber. An interface means connects the transport chamber to the process chamber. A transport means transports a semiconductor wafer from the transport chamber to the process chamber by way of the interface means. The transport means mounting a substrate is inserted into a communicating corridor including a supply means and an exhaust means. The substrate is transported while performing the supply and exhaust by sequentially controlling a supply shutoff means, an exhaust shutoff means, and a communicating shutoff means according to the position of a conductance part formed of a gap between the transport means and the communicating corridor. Thus, the substrate is transported at a high throughput without contamination of the substrate while keeping the different atmospheric conditions for the transport chamber and the process chamber, thereby manufacturing a semiconductor device with high performance capabilities.

摘要： A technique and exposure apparatus measures, with a high degree of accuracy, figure and placement errors of individual optical elements constituting optics embedded inside of an exposure apparatus or the like, with the optics kept in an embedded state as they are. The system measures the distribution of wavefront distortions in the optics while changing the positions of a light source and an image point inside an exposure field of the optics being observed. Optimal displacements of reflective surfaces constituting the optics are then found by calculation based on the measured distribution of wave-front distortions. Finally, the positions of the reflective surfaces are corrected in accordance with the calculated optimal displacements. The positions of the reflective surfaces are corrected by individually controlling displacements output by a plurality of actuators attached to each reflective surface and by mechanically modifying appropriate portions of the reflective surfaces.

摘要： A separation type optical head according to the present invention includes at least a light source portion for emitting collimated beams, a focusing device (a focusing lens) for focusing the collimated beams onto an information recording surface of an optical disc medium, a focal point control mechanism for the position of the spot on the information recording surface, and a photo-detection portion for receiving beams reflected by the information recording surface. The structure is divided into a fixed portion including the light source portion and the photo-detection portion and a movable portion including the focusing device (focusing lens) and the focal point control mechanism. At least the movable portion of the separation type optical head is movably accommodated n a frame (sealing case) for the optical head so as to prevent irregular vibrations of the movable portion due to high speed air flows or turbulence. Furthermore, a focal point control mechanism of an air float type may be employed in the movable portion of the separation type optical head so as to actively utilize the high speed air flow generated due to the rotation of the disc medium to perform a rough adjustment of the focal point of the focusing device.
