Inventor: IKEDA MINORU
IPC: H01L21/30
Filed: 1984-07-25
Abstract: PURPOSE:To enable to correct the positional deviation of a water chuck by performing a direct measurement, and to enable to perform the printing of patterns having few drifts, positional variations and an out-of-focus by a method wherein a plurality of cubic-cornered mirrors per measuring axis are arranged on a wafer chuck. CONSTITUTION:A wafer chuck 5 is mounted on the X-Y stage 1, to be used for a step-and-repeat operation through the intermediaries of a rotary atage and a titled stage. The laser interferometer 13 to be used for cubic-cornered mirrors is fixed on a base 7, the positional variation of the wafer chuck 5 is measured by a laser length-measuring device 9, and the X-Y stage 1 is feedback-controlled by an X-Y stage driving device 10. As a result, the drift of the X-Y stage 1, a rotary stage 2 and the tilted stage 3 can be corrected. A plurality of cubic- cornered mirrors 13 are fixed on the wafer chuck 5 at the same pitch as the feeding pitch of the step-and-repeat operation. As a result, drift can be corrected by the length measurement of laser even when any chip on the wafer is being exposed.

Title: Coating method
Inventor: TADA KEIJI
IPC: B05D1/02
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To form a uniform coating film of small film thickness having a very similar shape to that of the surface of particles to be coated, by using a spray nozzle having such a property that the frequency distribution of liquid drops having diameters of a specified multiple or more of the Sauter average particle size is a specified value or low to the all liquid drops. SOLUTION: When particulate substances are to be coated by using a spray nozzle, such a spray nozzle is used that the frequency distribution of liquid drops having diameters twice or larger as the Sauter average diameter is <=15 wt.% to the all liquid drops. If the frequency distribution exceeds this value, the purpose to uniformly coat particles with a thin film is not realized. Moreover, deposition amount of a resin on a device increases. The proportion is preferably <=5 wt.%, and more preferably <=1 wt.%. The kinds of the spray nozzle are not limited, and a flat spray nozzle, solid spray nozzle or the like can be used. The particulate material is not limited, and preferably it contains a fertilizer as the main component.

Filed: 1985-07-10
Abstract: PURPOSE:To smoothly supplement liquid helium by providing a bypass tube for an emergency valve of an exhaust tube from a liquid helium tank, and mounting an operation valve in the bypass tube. CONSTITUTION:Even if the pressure in a tank rises when supplying liquid helium 8, helium gas is exhausted through a piping system such as an exhaust tube 7, a bypass tube 13 and an exhaust duct 9 having pressure loss lower than a cooling tube 6 having larger pressure loss by opening the operation valve 14 of the tube 13. Accordingly, the pressure rise in a liquid helium tank 1 is suppressed, and sufficient pressure difference can be obtained to a liquid helium supply source 1. Thus, the supplying speed of the liquid helium to the tank can be sufficiently obtained.

Title: Rotary dresser
Inventor: MINEO KIYOTAKA
IPC: B24B53/14
Filed: 1982-09-03
Abstract: PURPOSE:To improve the cutting quality and working accuracy of a correcting grinder and improve the operational efficiency by forming a plurality of projecting stripes on the whole outer periphery and planting in a line diamond particles or compacts onto each projecting stripe, and increasing the amount of corrected works. CONSTITUTION:Grooves are formed on a grinder surface, corresponding to the projecting stripe 4b on a dresser having each diamond 6 as apex, by revolving the dresser and pressing said dresser onto a revolving grinder. That is, the sectional shape having wave form on the rotary dresser is transferred onto the grinder surface, and when a traverse system is applied, said groove is formed in titled spiral form. Therefore, the grinder is brought into contact uniformly onto the whole surface of an article to be worked, and wave-shaped unevenness is not formed on the article to be worked. Since the wave-shaped unevenness is formed in repetition on the grinder surface, the grinding resistance is low, and the cutting quality is superior, and the grinding accuracy and the working efficiency are improved.

Title: Surface protective film or sheet
Inventor: OKUMURA KAZUTO
IPC: B32B7/02
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent a float phenomenon from being generated even though a surface protective film or sheet is restored to ordinary temperature by thermopressure fixing with an autoclave or the like by a method wherein a film in which oxygen permeability at specific temperature and specific relative humidity is under specific numerical value is used as a base material, and a pressure-sensitive adhesive layer is provid on its one side. SOLUTION: A film of 25 μm thickness consisting of ethylene-vinyl alcohol copolymer is used as a base material film. One side surface of the film is treated with corona, and a pressure sensitive adhesive is applied to this surface. Though a permeation amount of oxygen receives influences from a thickness of the film, temperature and humidity, the permeation amount is inversely proportional to the thickness of the film, and linearity is realized between a logarithm of the permeation amount and a reciprocal of absolute temperature. Though oxygen transmission at temperature and pressure under the same conditions as those for an autoclave is intrincically important, when a film wherein oxygen permeability at 20 deg.C and 0%RH is under 40 cc/m<2> 24 hrs-atm (a film wherein oxygen permeability at ordinary temperature, ordinary humidity, and ordinary pressure is very low) is used as the base material, occurrence of float is very little.
