Title: Lighting optical system
Inventor: TORIGOE MAKOTO
IPC: H01L21/027
Filed: 1984-05-02
Abstract: PURPOSE:To obtain the lighting optical system which transfers a fine pattern image with no distortion to a wafer by providing a means for Koehler illumination with light from a light source, a means which is arranged on an irradiated surface of the Koehler illumination and controls the light into an arcuate shape, and a means which projects the image from the control means upon a specific surface. CONSTITUTION:The light emitted by the extrahigh pressure mercury lamp 1 is converted on a light integrator 3 through an elliptic mirror 2. Further, light from respective points of the light integrator 3 is collimated through a collimator lens into a parallel light beam, which illuminates the surface of an arcuate slit 5 for the Koehler illumination with number of pieces of luminous flux. Further, the luminous flux passed through the arcuate slit 5 is projected on the surface of a mask 7 by an arcuate slit image formation optical system 6 to form a semiarcuate unirradiated area. Thus, the arcuate slit 5 is arranged in the irradiated surface of the Koehler illumination and the image of this arcuate slit 5 is formed on the surface of the mask 7, so there is not an effective light source image formed on the mask surface like before and the patten image transferred to the wafer, therefore, has no distortion.

Abstract: PURPOSE:To reduce variations of a magnetic characteristic as well as to enable the steps such as abrading to be removed, by compacting and sintering magnetic powder and then plastic deforming the compact prior to the heat treatment of it. CONSTITUTION:The magnetic powder is pressed and compacted under the application of the magnetic field. Then, while or after sintering it, the compact is plastic deformed and is heat=treated for providing magnetism. For example, the alloy powder consisting of 36.4wt% of Sm and the rest wt% of Co is pressed and compacted (compact pressure 4TON/cm<2>) under 6KOe magnetic field. Then, the sintering under the condition of 1,110 deg.CX1Hr is accomplished in an H2 gas so as to obtain a sintered material having the dimensions of 64X2X14mm. This sintered material is hot deformed in an inert gas and an Ar gas under the temperature of 1,060 deg.C so as to allow the neutral surface having 14mm anistrophic direction to have a curvature of 85mm radius. Then, after the heating of it under the condition of 950 deg.CX1Hr is carried out in the Ar gas, this sintered material is gradually quenched to 800 deg.C at the speed of 1 deg.C/min and is quickly quenched to the room temperature. Next, this quenched material is machined to be the arc segment magnet (outside radium 90, inside radius 80, thickness 20mm, arc angle 39 degrees) shown in the figure.

Abstract: PURPOSE:To control the quantity of etching precisely by the change of the strength of fluorescence emitted by a method wherein rays are irradiated to the dissolving portions of crystals during wet etching. CONSTITUTION:Ga0.9Al0.1As12, Ga0.7Al0.3As 13 is grown on GaAs 11 in an epitaxial shape. A sample the same as the substrate 1 is prepared, Ar laser rays with 4,890Angstrom  are irradiated, the strength of fluorescence with 6,900Angstrom  emitted from the layer 13 is made 1, and a thickness-fluorescence strength curve is formed. Since the wavelength of fluorescence emitted from a layer 12 is 8,100Angstrom , only fluorescnece with 6,900Angstrom  emitted from the layer 13 is detected by a spectrometer 5, and the change of strength can be detected. The layer 13 is selectively etched by an etching liquid 8 belonging to a phosphoric acid group. A thickness-fluorescence strength curve previously obtained is referred at that time, and the layer 13 with fixed thickness is acquired when pulling the substrare 1 up from the etching liquid 8 if the strength agrees with fixed fluorescence strength. According to this constitution, the quantity of etching can precisely be controlled even if the etching liquid and an etching condition minutely change becuase the change of the thickness of the layer to be etched is detected at all times.
