  • Method for manufacturing a substrate having window-shaped coating films and frame-shaped coating film on the surface thereof
    Patent number: 5561011
    Abstract: A method for manufacturing a substrate having electrically conductive circuits on the surface of a transparent substrate, window-shaped coating films on the electrically conductive circuits and a frame-shaped, functional coating film at the regions not occupied with the window-shaped coating films, includes the steps of:(a) coating the surface of a transparent substrate with a photoresist composition to cover the circuits-carrying surface of the substrate, followed by forming a photoresist coating film,(b) superposing a photomask on the surface of the photoresist coating film formed through step (a) and exposing the thus masked photoresist coating film to light,(c) subjecting the substrate formed through steps (a) and (b) to development, and eliminating the photoresist coating film in the frame-shaped part,(d) subjecting the photoresist coating film left in step (c) to heat-treatment,(e) coating the substrate obtained through steps (a) to (d) in this order with a negative photoresist composition containing a
