Patent ID: 7014885

Claim:
A method for creating a deposit of a material of interest on a receiving substrate, the method comprising the steps of providing a first laser and a second laser, wherein the first laser is a pulsed laser, providing a receiving substrate, providing a target substrate comprising a laser-transparent support having a back surface and a front surface, wherein the front surface has a coating that comprises a source material, wherein the source material is either a single compound or a homogenous mixture of different compounds that can be transformed into the material of interest, positioning the first laser in relation to the target substrate and exposing the target substrate to pulsed laser energy so that the pulsed laser energy is directed through the back surface of the target substrate and through the laser-transparent support to strike the coating at a defined target location with sufficient energy to cause the source material to be removed from the surface of the support at the defined location, positioning the receiving substrate in a spaced relation to the target substrate so that the source material is deposited at defined receiving location on the receiving substrate, and positioning the second laser in relation to the receiving substrate so that laser energy strikes the deposited source material to transform the source material into the material of interest; wherein the first laser has an energy and wavelength chosen to vaporize one or more monolayers of the source material adjacent to the target substrate without vaporizing the rest of the source material.
