Title: Optical device for alignment
Inventor: KATO KINYA
IPC: H01L21/027
Filed: 1985-04-04
Abstract: PURPOSE:To prevent an image of a body to be detected from shifting or deviating on its image plane in focusing operation by aligning the optical axis of a focusing lens group almost with the main light beam of parallel luminous flux from a collimator lens group. CONSTITUTION:Oblique luminous flux (a) from an alignment mark A and an alignment reference mark B is image-formed at the rear-side focus position of a lens 6 through objectives 5 and 6. Luminous flux from a position B1 is converted by a positive collimator lens 7 into parallel luminous flux a1, which is image-formed again as an image B2 of both marks A and B on a screen 9 through an image forming lens 8. Therefore, the image B2 is observed through an image pickup device 12; and the image B2 is focused by moving the screen 9 and objective 10 in one body and a wafer 1 and a reticle 4 are positioned by moving either of the wafer 1 and reticle 4. At this time, the main light beam is made incident on the screen 9 at right angles, so the image B2 neither shifts nor deviates on the screen 9.

Title: Method and device of narrow groove welding
Inventor: SHIMADA WATARU
IPC: B23K9/00
Filed: 1979-06-07
Abstract: PURPOSE: To make possible even welding by injecting arc-control gas toward the arc produced between filler core and base metals while controlling the same into pulse-form thereby moving and controlling the arc position.  
     CONSTITUTION: This is the method and device of welding for narrow groove welding, particularly welding of a small groove gap. A torch body 10 is disposed coaxially to a contact tip 14 and a filler core 16 is disposed axially slidably to the contact tip in the state that it is electrically contacted therewith. Welding current flows between the filler core and base metals 18 to form an arc 20. Shielding gas 22 is led from between a shielding cover 12 and contact tip, whereby welding action is done. On the other hand, a gas flow passage 24 consists of a number of through-holes penetrated along the axial direction and is tilted toward the filler core. Hence, the arc shape is deformation-controlled by the arc control gas 26 which is injected from the gas flow passage.

Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a charged particle beam device with which accuracy of position of the charged particle beam relative to change in temperature can be improved without providing a specially large-scale apparatus. SOLUTION: Temperature detected by temperature sensors 20 and 21 varies with change of ambient temperature. Amount of position compensation of the beam shift is calculated by a calculator 22 according to the change in temperature detected by the temperature sensors 20 and 21. The result is supplied to a low-pass filter 23 which cuts components higher than a specified frequency. Signals from the low-pass filter 23 is supplied to a control circuit 24. The control circuit 24 controls a deflector controlling circuit 19 according to the supplied position compensation amount Cx, and supplies deflection signals to an electrostatic deflector 18 for compensating the beam shift. As a result, even if ambient temperature or so changes, the resulting beam shift is completely compensated. Since electron beam EB is always incident on a specified position, an electron beam writing is performed with a high accuracy.
