Title: Formation of fine patterns
Inventor: YAMASHITA KAZUHIRO
IPC: H01L21/027
Filed: 1995-05-31
Abstract: PURPOSE: To make it possible to prevent pattern inclination by selectively forming oxidized metallic films or silylated films on a resist surface and dry etching the resist with these selectively formed films as mask. CONSTITUTION: The surface of a semiconductor silicon substrate 105 is spin- coated with a resist 104 to form a resist film. Next, the patterns on the mask 102 are exposed by using an KrF excimer laser 101 to generate an acid. The surfaces of the exposed parts of the resist are changed to have hydrophilicity by such generation of the acid, and left as it is thereby, steam 106 is a adsorbed on the exposed part surface of the resist and water is diffused. Further, the vapor 108 of methyl triethoxysilane is sprayed for three minutes to the resist surface to selectively form the oxidized films 109. Next, the resist is heated to evaporate the generated alcohol and the unreacted water and to cure the selectively formed oxidized films 111 to form the mask. The resist is etched by using O2 RIE112 to form the patterns.

Title: Production of antimony-doped single crystal
Inventor: KIDA MICHIO
IPC: H01L21/18
Filed: 1986-06-09
Abstract: PURPOSE:To obtain the title single crystal having a uniform concn. of antimony in good yield by specifying the pressure in a vessel at the time of pulling up a single crystal from a polycrystal melt added with antimony in the reduced- pressure vessel. CONSTITUTION:The pressure in the vessel is controlled to 40-100Torr, when an antimony-doped single crystal is pulled up from the silicon polycrystal melt added with antimony in the reduced-pressure vessel. The supply of gaseous argon into the vessel is simultaneously increased to sufficiently discharge silicon oxide. Consequently, the vaporization of antimony from the melt is reduced to suppress the variation in the antimony concn., and an impediment of the single crystal growth due to the solidification of antimony vapor is prevented, and the yield from the raw material is improved.

Title: Wire housing duct
Inventor: MIZUNO SHUJI
IPC: H02G3/04
Filed: 1995-05-31
Abstract: PURPOSE: To simply prevent noises from a noise producing source from entering wires or cables by placing electrostatic shielding plates inside a duct. CONSTITUTION: Wires within a distribution board are placed in a lengthwise resin duct body 1 having a U-shaped cross section. The duct body is covered with a flat plate-shaped duct cover 2, and then electrostatic shielding plates 3 lined to the duct body 1 and duct cover 2 are grounded through a terminal 5. The wires placed in the duct body 1 lined with the electrostatic shielding plates 3 are in the same situation as those encircled with conductors. As a result, any noise externally produced goes to ground through the electrostatic shielding plates 3 inside the duct body 1; therefore, the harmful effect of the noise on the wires themselves is prevented. The electrostatic shielding plates 3, 4 may be boards or meshes, such as wire netting.  This makes it possible to rationally install wires within a distribution board without considering diaphragm distance from a noise producing source, and to simply prevent the influence of noise.

IPC: G06T17/40
Filed: 1988-05-31
Abstract: PURPOSE:To freely decide whether a cut 3-dimensional pattern is displayed with its inner part or front part left centering on the cutting plane by leaving only the 3-dimensional pattern on a display screen for display at the side that is defined by the cutting plane shown by the cutting position information. CONSTITUTION:In case a switching part 6 decides to display a cut 3-dimensional pattern with its inner part left centering on the cutting plane, only the graphic data corresponding to the value (z) larger than the reference value is validated at a comparing part 122. In case said 3-dimensional pattern is displayed with its front part left centering on the cutting plane, only the graphic data corresponding to the value (z) smaller than the reference value is validated and outputted to a (z) buffer.algorithm part 13. Thus it is possible to freely decide whether the cut 3-dimensional pattern is displayed with its inner or front part left centering on the cutting plane.

Title: Pattern forming method
Inventor: AKIMOTO SEIJI
IPC: G03F7/039
Filed: 1983-07-22
Abstract: PURPOSE:To improve the throughput of an electron beam exposure device by using a specific copolymer film, irradiating the film with an electron beam selectively and decomposing into a low-molecular weight polymer, and removing it selectively with a solvent and obtaining a positive pattern. CONSTITUTION:The film of a copolymer of alpha-cyanoalkyl acrylate (CAA) and alpha-methylstyrene (MST) or its derivative is used and irradiated with the electron beam (EB) selectively to make the irradiated area into the low-molecular weight polymer, which is dissolved and removed selectively with the solvent to obtain the positive pattern consisting of said copolymer. This alphaCAA-alphaMST copolymer consists of high-sensitivity alphaCAA and alphaMST having superior resistance to plasma, so resistance to dry etching and keeping quality are excellent. Then, the positive type resist pattern with good sensitivity is formed by said EB irradiation and the throughput of the EB exposure device is improved. Further, the dry etching resistance of the resist pattern is improved, so the thickness of the resist film is decreased and the resolution of the pattern is improved.
