Title: Detecting method of mark position
Inventor: GOTOU YOSHIAKI
IPC: H01L21/027
Filed: 1979-12-12
Abstract: PURPOSE:To perform the detection of positions with a small volume of information in a short time by a method wherein a slit-shaped rectangular beam is scanned on the region including the positioning marks to the directions of axles X and Y and the positions on the X and Y directions are found from the deviation of the reflected signal in each axial direction. CONSTITUTION:The slit-shaped rectangular beam 13 is irradiated on the whole row and the volume of the reflected electronic signal is detected and memorized. The same procedure is performed as far as to the Yn row. Then the scanning point of the Y1-Yn is irradiated once with the rectangular beam 13' to be used for irradiation of the whole X1 column and its reflected signal is memorized. The same procedure is performed repeatedly to the direction of the X axis as far as Xn column. The signal volume of each scanning position is compared and the coordinates (Xi and Yj) of the centroid of the positioning mark 1 can be found when the coordinates Xi and y3 which give maximum displacement is obtained for each scanning position. Consequently, as the slit-shaped electronic beam is scanned, the number of scanning, the volume of information and the processing time of a computer can be greatly reduced.

Abstract: PURPOSE:To effectively separate a phosphate ion from a phosphate ion- containing aq. soln. having a wide concn. range without using a large amt. of an org. solvent by bringing the phosphate ion-containing aq. soln. into contact with a cation exchange resin of a divalent or more cationic ion. CONSTITUTION:When a phosphate ion is separated and removed from a phosphate ion-containing aq. soln. mixed with other anions e.g. nitric acid, sulfuric acid or halogen, such as the byproduct gypsum washing waste soln. of a wet phosphoric acid manufacturing factory, the phosphate ion-conaining aq. soln. is brought into contact with a cation exchange resin of a divalent or more cationic ions. In this case, as the cation exchange resin of the divalent or more cationic ions, pref., a divinylbenzene 2-9 magnetic field gel type cation exchange resin is used and a porous cation exchange resin having pores whose pore size in the max. pore volume is 800nm or less is used. By this constitution, the phosphate ion is selectively adsorbed without precipitating hardly soluble phosphate.

Abstract: PURPOSE:To supply a semiconductor device which can obtain a smaller series resistance device by forming a higher resistance layer than the resistance of a semiconductor substrate ion-implanting impurity of reverse conductivity type against the semiconductor substrate on the main surface of one conductive type semiconductor substrate. CONSTITUTION:The main surface of a semiconductor substrate 1 is a plane (111) and is N type which includes As as impurity, the resistivity being 0.001- 0.003OMEGA-cm. On the one main surface of the semiconductor substrate, i.e. the surface of epitaxially grown layer, boron is ion-implanted as reverse conductive impurity and an implanted layer 2 of relatively high resistance is formed. The semiconductor substrate is annealed for 30min at a temperature of 1,000 deg.C. Then, an N type epitaxial layer 3 of 1OMEGAcm resistivity is grown in thickness of 3mum by a normal epitaxial growth process using monosilane which includes phosphorous as a doping agent. This enables obtaining steep variation of carrier concentration profile at the interface of the epitaxial layer and the semiconductor substrate and manufacturing a wafer suited to obtain a smaller series resistance device.

Abstract: PURPOSE:To secure the length of a pointer with good visibility by arranging an advancing direction changing means for an incident light beam on the light beam incident surface side of a display board. CONSTITUTION:As to the pointer P1 which indicates a lower limited value on the lower edge 10b side of the display board 10, the pointer is formed by allowing the light beam 12a to advance as shown by an alternate long and short dash line when a hologram 15b is not used, but it is formed by allowing the light beam to advance as shown by a continuous line in a figure in the case that the hologram 15b is provided. Namely, the actual center of rotation 20 of the pointer P1 exists at the position of a mirror 14 which is rotated by a movement 13. However, the center of the rotation is viewed by the hologram 15b as if it exists at the focusing position of the virtual image of a point 12. Therefore, the center of rotation 20 is raised to the lower edge 10a side of the display board 10 like the point 21 by interposing the hologram 15b and the length of the pointer is viewed longer than in a conventional manner even in the case of providing a mask.

IPC: G03B27/16
Filed: 1992-05-28
Abstract: PURPOSE:To obtain a contact type printer obtained by simplifying the cleaning of a glass plate for exposure and a Fresnel lens and facilitating the maintenance thereof. CONSTITUTION:The Fresnel lens 34 collimating light from a light source 85 and the glass plate for exposure 31 on which an original is placed are supported by a coupling supporting part 37 by giving a prescribed distance, and an interval between them is set as an optical path chamber 67 whose inside is made airtight by a sealing member. Then, air passed through a suction filter is sent to the chamber 67 from a cooling fan 121. As a result, dust or air including the component of ammonia gas or the like does not enter the chamber 67. Besides, even when the dust or the like slightly enters, it is exchanged to the cleaned air. Thus, since the dust or the like is not attached on the surface of the lens 34 or the inside surface of the transparent plate for exposure faced to the optical path chamber, the lens 34 and the plate 31 need not be cleaned.

Title: Etching method
Inventor: TERAMAE JUNICHI
IPC: H01L21/308
Filed: 1989-06-23
Abstract: PURPOSE:To suppress attachment of fine dust particles to a wafer immediately after processing by a method wherein when a silicon oxide film provided on a silicon substrate is to be etched, hydrofluoric acid with surface active agent to be specific contact angle added is used. CONSTITUTION:When a base oxide film formed on an Si substrate is to be removed and a thermal oxide film is formed to be a gate oxide film, hydrofluoric acid with surface active agent with contact angle of 15 to 30 degrees added is used to remove the base oxide film. If the amount of added surface active agent is too small, the contact angle is large resulting in poor wettability exhibiting water repellency while if the amount is too large the contact angle is small resulting in good wettability exhibiting hydrophilicity. Therefore with small contact angle, attachment of dust particles is reduced but side reaction increases at 15 degrees or less. If the angle exceeds 30 degrees, attachment of the dust particles is rapidly increased, Therefore by optimizing the amount of added surface active agent, attachment of dust particles onto a wafer can be controlled.

Abstract: PURPOSE:To obtain a W/O emulsion composition extremely stable over a wide temp. range, by using a propylene oxide/ethylene oxide adduct having a propylene oxide chain present therein and containing an alkyl group as branched group. CONSTITUTION:A propylene oxide/ethylene oxide adduct [e.g., polyoxyethylene (15)polyoxypropylene(8)-2-tetradecyl-octadecyl ether] represented by formula (wherein a is an integer of 7-19, b is an integer of a+2, m is a number of 5- 30 in an average addition mol number and n is a number of 5-30 in an average addition mol number) is contained in an amount of 0.1-20wt% of the total amount of a W/O emulsion composition. This W/O emulsion composition has extremely good storage stability over a wide temp. range. Especially, polar oil such as triglyceride being a sebum analogue component, which could not be compounded conventionally even if desired to be compounded because stability at ambient temp. was inferior, can be prepared as an extremely stable W/O emulsion composition.
