10.1 Introduction

Ever since the laser-induced forward transfer (LIFT) technique was first used to print ink [1] and then copper patterns [2] onto a substrate, it has been demonstrated in a wide range of materials such as inorganics, organics, and multicomponent systems. Traditionally, LIFT employs a donor substrate of which one side is coated with a solid thin-film layer. The laser fluence (energy/area) that is required to propel a portion of this solid film layer from the donor across the gap to ...
