Title: Scanning aligner and scanning exposure method
Inventor: TOUKI TATSUHIKO
IPC: G03F7/20
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To elevate the accuracy in alignment of a wafer by continuously detecting the quantity of dislocation in the scanning direction of a primary deflection grating on a reticle and the secondary deflection grating in a chip region. SOLUTION: A one-dimensional diffraction grating 3 on a reticle is irradiated with alignment beams 1a and 1b, and the primary beam of the diffraction grating which has passed this and has the, positional information in X direction of the reticle is condensed in the two-dimensional diffraction grating 11 on a chip region 10 through a projective lens 7. The reflected diffracted light which is reflected from the grating 11 and has the positional information in X direction of a chip is entered into a light receiving element 5 through a projective lens 7 and a reflective mirror 6, and it is converted into an electric signal so as to adjust the position of the wafer.  Since the beam of different wavelength from an exposure beam is usually used as an alignment beam so that the alignment beams 1a and 1b may not expose photoresist, the image pickup relation between the reticle and the wafer differs between the alignment beam and the exposure beam, and color aberration arises. To compensate it, a color aberration compensating mechanism 4 using, for example, a lens or a prism is used.

Filed: 1977-11-29
Abstract: PURPOSE: To make possible detection of minute leakage at high sensitivity by flowing an inert gas in te welded bellows of a control rod driving device, drawing out the liquid metal having leaked through the bellows in the state of aerosol to the outside of the apparatus thereby detecting the same.  
     CONSTITUTION: A vent hole 18 is provided near the bottom end of an operating cylinder 8 and a helical tube 19 is connected in the hole opened in the moving plate 10 at the top end thereof. A lead-out tube 20 is installed through the fixifng plate 17 of the cylinder 3 and its bottom end communicates with an inner chamber 14. When with a control rod driving device CRD 23, an Ar gas is forcefed through the inlet 21 of the tube 19, it flows out through the vent hole 18 of the cylinder 8. This gas washes the inside surface of a welded bellows 6 and diffuses in the inner chamber 14. If at this time the liquid metal existing on the outside of the bellows 6 leaks and enters, fine particles of metal oxides are produced. These particles pass through the tube 20 and are discharged to the outside of the cylinder 3. Even a slight amount of leakage may be detected with the detector for metal liquid of high sensitivity connected to the end of the tube 20, thus heavy leakage may be prevented before it occurs.
