Abstract
A method of depositing conducting patterns on a large area surface is disclosed. The method is characterized by photochemically depositing an electrically conducting organic .pi.-electron donor compound on an insulating surface and selectively depositing a metal onto the established conductive pattern while simultaneously removing the organic film.
Claims6
A method for depositing metal conducting patterns on large area surfaces including the steps of:
- a. photochemcially depositing organic .pi.-electron donor-halide salt onto a substrate in a predetermined pattern and
- b. simultaneously electrolytically depositing a metal film according to said predetermined pattern while removing said organic .pi.-electron donor halide salt.
