PHOTO-SELECTIVE ELECTROLESS METAL-DEPOSITION FOLLOWING LIGHT-ABSORPTION BY TITANATE CERAMICS

Light absorption by titanate ceramics which have been pretreated with a Sn+2 containing solution can deactivate an electroless plating catalyst providing that photo-exposure occurs in an 02 containing ambient. Conditions are described whereby a lead zirconate-titanate ceramic can be photopatterned by a brief exposure to a 365 nm wavelength lamp using a Mylar photomask and electroless Ni plated to yield a Ni pattern on the ceramic. Line/space resolution exceeding 0.05 mm is attainable. © 1990, The Electrochemical Society, Inc. All rights reserved.
