Abstract: PURPOSE:To provide a method of manufacturing a semiconductor device excellent in an embedding characteristic of an insulation film for a space between patterns. CONSTITUTION:Under conditions of covering a first pattern 11 of a basic 10 and a second pattern 12 formed on the upper surface and having a flange part 12a projected from the first pattern, an etching stop film 13 is formed on a surface of the basic 10. Next, a shape-regulating film 14 is formed on this surface under conditions that the surface of a side of the first pattern 11 of the shape-regulating film 14 is disposed outwardly the surface of the etching stop layer 13 of the side of the flange part 12a. Thereafter, the shape-regulating film 14 of the other portions is removed by anisotropic etching under conditions that the shape-regulating film 14 is left downwardly of the etching stop film 13 of the side of the second pattern 12. As a result, an insulation film 15 is formed under conditions of covering the first and second patterns 11, 12 and having a surface higher than the upper surface of the second pattern to obtain a semiconductor device smoothing the surface.

Abstract: PURPOSE:To raise the accuracy of measurement of a minute sample, by providing a sample chamber with a light condenser for measuring the minute sample. CONSTITUTION:A sample chamber 2 is equipped with a light condenser 15, which comprises a condenser light source 16, convex reflectors 17, 20, concave reflectors 18, 19 and an optical path switching mirror 21 and serves to measure a minute sample. When the optical path switching mirror 21 is swung out of an otpical path for the sample light 10 of a spectrophotometer light source 4 located in a light source chamber 1, ordinary spectrophotometric measurement is performed. When the switching mirror 21 is swung into the optical path for the sample light 10, this light is intercepted and the light of the condenser light source 16 is transmitted to the minute sample through the convex reflector 17 and the concave reflector 18 and then conducted to a spectroscope chamber 3 through the other concave reflector 19, the other convex reflector 20 and the switching mirror. A minute condensed light image is thus formed only by shifting the optical path switching mirror 21. Spectroanalysis can be performed while confirming the spectral accuracy. This results in attaining the purpose.

Filed: 1994-06-10
Abstract: PURPOSE:To easily command the attitude of a tool spindle with respect to the tool spindle attitude control system for a numerical control machine tool to work a work while inclining the tool spindle on a three-dimensional space. CONSTITUTION:A preprocessing means 102 reads out a working program 101 and decodes a tool spindle attitude control mode and a tool spindle attitude vector command. While using tool spindle attitude vector commands (I, J and K) transmitted from the preprocessing means 102 in the tool spindle attitude control mode, a spindle rotating angle arithmetic means 103 calculates the respective rotating angles of rotary spindles to decide the attitude of a tool spindle. This arithmetic is performed according to a prescribed operation expression decided by a parameter Pa set for each machine constitution pattern of the numerical control machine tool. An interpolating means 104 reads the rotating angle of two rotary spindles, performs interpolation for operating two rotary spindles just at that rotating angle and interpolates X, Y and Z axes. A programmer can easily perform programming for three-dimensional working only by commanding the tool spindle attitude vector commands (I, J and K).
