METHOD FOR MANUFACTURING SUBSTRATE FOR ELECTRON BY METHOD WHEREIN TWO-LAYER OR THREE-LAYER STRUCTURED ELECTRICITY-CONDUCTING BODIES ARE VERTICALLY ARRAYED AT SUITABLE POSITIONS IN CONTAINER OF SUITABLE SHAPE AND SIZE, FIRE RETARDANT, HEAT RESISTING AND INSULATION RESISTING NATURALLY SETTING RESIN, FIRE RETARDANT, HEAT RESISTING AND HEAT INSULATION RESISTING THERMOPLASTIC RESIN, OR MIXTURE WHEREIN EACH AND FILLER (SiO2, ALO2, ZrO2 AND THE LIKE) ARE BLENDED IN SUITABLE RATIO IS HEATED TO SUITABLE TEMPERATURE, CAST INTO THE CONTAINER (MOLD) AND CURED BY COOLING OR THE LIKE

摘要

PROBLEM TO BE SOLVED: To technically solve a necessity wherein for a substrate for electron a very thin good conductive wire is vertically buried or filled by passing through the substrate at accurate positions in a minimum pitch. SOLUTION: Two layer or three layer structured electricity-conducting bodies are vertically arrayed at suitable positions in a container (mold) of a suitable shape and size. A fire retardant, heat resisting and insulation resisting naturally setting resin, a fire retardant, heating resisting and insulation resisting heat insulation resisting thermoplastic resin, or a mixture wherein each and a filler (SiO2, AlO2, ZrO2 and the like) are blended in a suitable ratio, is heated at a suitable temperature, cast into a container (mold), and cured by cooling.
