Title: Plating method and surface treating solution usable therefor
Inventor: OKANO TATSUHIRO
IPC: C23C18/32
Filed: 1990-09-06
Abstract: PURPOSE:To selectively form a plating film on an electrically conductive transparent film by electroless plating without using any fluoride by activating the electrically conductive transparent film with an aq. alkali soln. contg. dissolved Pd salt and then carrying out electroless plating. CONSTITUTION:A patterned electrically conductive transparent film on a transparent insulating substrate is immersed in a surface treating soln. prepd. by dissolving Pd salt in an aq. soln. of alkali such as NaOH and metallic Pd is stuck on the electrically conductive transparent film. A metal such as Ni is then selectively deposited on the electrically conductive transparent film by electroless plating with the metallic Pd as a catalyst.
