BINDER DIFFUSION PATTERNING OF A THICK FILM PASTE LAYER

摘要

The present invention concerns a process for the fabrication of electrical and electronic devices. A polymer film is patterned on a substrate. A thick film paste is deposited over the patterned polymer. The thick film paste is dried under conditions which allow diffusion of the polymer into the thick film paste. This renders the diffused area insoluble in alkaline development solution.
