Paper Abstract
In this work, we detail the basic mechanisms and potential applications of the Laser Induced Forward
Transfer (LIFT) for the rapid deposition and patterning in a clean environment, of high Tc superconducting thin
films. With the LIFT technique, a stoichiometric oxide superconductor compound is initially deposited in a thin
layer on an optically transparent support. By irradiating, under vacuum or in air, this precoated layer with a
strongly absorbed single laser pulse through the transparent support, we are able to remove the film from its
support to be transferred onto a selected target substrate, held in contact or close to the original film. The
mechanisms for transferring YBaCuO and BiSrCaCuO thin films, with a pulsed UV excimer laser are described
using a thermal melting model based on the resolution of the heat flow equation. The various possibilities given
by the LIFT technique for patterning high Tc films (mask and direct patterning) are also examined.
