1. INTRODUCTION
The application of laser forward transfer techniques has steadily grown
since the first reports of patterned copper deposition by Bohandy, et al. 20
years ago (Bohandy, 1986). These general techniques employ a pulsed laser
to locally transfer material from a source film onto a substrate in close
proximity or in contact with the film. The source is typically a coated laser-
transparent substrate, referred to as the target, donor, or ribbon. Laser pulses
propagate through the transparent ribbon until they are absorbed by the film.
Above an incident laser energy threshold, material is ejected from the film
and transferred toward the acceptor, waiting or receiving substrate. These
