MULTILAYER WIRING BOARD AND METHOD FOR MANUFACTURING THE SAME

摘要

In a multilayer wiring board, on an insulating board (10), an arbitrarily formed first conductivity type pattern (12), an insulating material layer (16A) and a second conductivity type pattern (20) formed by applying a conductive material in a pattern on a region corresponding to a graft polymer pattern (18) formed on the insulating material layer are subsequently provided. The multilayer wiring board is provided with a conductive path (22) which electrically connects the first conductivity type pattern and the second conductivity type pattern existing on the insulating substrate. The graft polymer pattern consists of a region wherein a graft polymer exists and a region wherein the graft polymer does not exist, or it consists of a region wherein a hydrophilic graft polymer exists and a region wherein the hydrophobic graft polymer does not exist.
