Title: Semiconductor device
Inventor: NISHIMURA HISAHARU
IPC: H01L21/3205
Filed: 1988-05-18
Abstract: PURPOSE:To shield a semiconductor device from adventitious noises by a method wherein a wiring layer necessary to shield from noises is covered with an upper wiring layer and a lower wiring layer connected with the upper wiring layer through an interlaminar insulating film to keep the wiring layer at a ground potential. CONSTITUTION:A P-type diffusion layer 3 optional in width and length is formed inside an N-type epitaxial layer 1, and a lower wiring metal layer 4 is formed on a silicon dioxide film 2 above the central part of the diffusion layer 3. Moreover, the part of the interlaminar insulating film 5 formed on the opening part of the silicon dioxide film 2 is selectively opened, and furthermore an upper wiring metal layer 6 is evaporated on the surface of a semiconductor device. Therefore, noises penetrating from peripheral circuits or the outside are shut off by the upper wiring layer 6 and a lower wiring layer composed of the P-type diffusion layer 3 or a conductive polycrystalline silicon layer 2 and can be conducted to the ground. By these processes, the inner wiring layer 4 can be free from the effect of noises, so that a faithful signal almost free from noises can be transmitted.

Title: Surface treatment of concrete ground
Inventor: SUMINO MASAHIRO
IPC: C04B41/65
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To treat a concrete ground in any time of a wet or dried state by approximately penetrating a sealer material obtained by diluting a water-soluble epoxy resin with water into the concrete ground, reapplying the sealer material to the concrete ground, coating the surface of the concrete ground with a composite material prepared by mixing a water-soluble epoxy resin with a cement mortar and applying a finishing material for coated floor after hardening of the composite material. SOLUTION: A water-soluble epoxy resin is dissolved or dispersed in water and mixed with a curing agent to form a resin layer which is reacted and cured even in the presence of water or under alkali conditions. To a dried concrete ground, a sealer material having extremely excellent permeability is penetrated into the concrete ground so that the material is firmly integrated into the concrete ground. To a wet concrete ground, since the sealer material and the epoxy resin are water-soluble, they have excellent compatibility with the concrete ground and strongly attached and integrated to the concrete ground. Further, the composite material is firmly attached to an epoxy resin, a urethane resin, or the like, of the finishing material for coated floor.

Title: Manufacture of semiconductor device
Inventor: KANAZAWA KENICHI
IPC: H01L21/8234
Filed: 1988-05-20
Abstract: PURPOSE:To reduce cell area and deterioration of write by forming a side wall only on a gate sidewall of a periphery transistor section execpting the cell transistor section of a nonvolatile memory to make an LDD structure. CONSTITUTION:A side wall 18 is formed only on a polysilicon gate side wall of a peripheral transistor section 14, and not formed on a cell transistor section 13. Therefore, only the peripheral transistor section 14 can be formed in an LDD structure. Since the side wall 18 does not extend crosswise at the cell transistor 13, the interval between the cell transistor and an electrode window 21 can be made small, thus allowing a small cell area. Moreover, write function does not deteriorate because the cell transistor section 13 is not of LDD structure.
