FORMING/MANUFACTURING OF INSULATING FILM, PRINTED WIRING BOARD, AND MANUFACTURING METHOD FOR PRINTED WIRING BOARD

摘要

PROBLEM TO BE SOLVED: To form an insulating film on the inside of minute through-holes formed in a conductive substrate. SOLUTION: An insulating film forming method has an immersion step for immersing a substrate into one-substituted trialkoxysilane solution, and an ultraviolet-light irradiating step in which the immersed substrate is irradiated with ultraviolet light so as to make one-substituted trialkoxysilane deposited on the substrate surface into a polysiloxane film.
