LASER-JET PLATING OF GOLD AND COPPER: MECHANISMS AND RECENT RESULTS.

Abstract

Summary form only given. The authors have analyzed data for laser-jet gold and copper electroplating obtained with a two-electrode galvanostatically controlled system. They have measured experimentally obtained deposition height/area and determined the reduction current/area required for the metallic deposit. The ratio of this current density to the total current density flowing in the system defines the plating efficiency. Also, recent data on laser-enhanced jet plating of gold and copper have utilized new jet cell configurations as well as several nozzle diameters. Use of optical fibers to guide the laser into the jet stream has also been undertaken. Results for these experiments are summarized. Some cross-sectioned jet and laser-jet copper deposits are shown and their structure compared.
