Abstract:
A method of depositing a patterned layer of material onto a substrate comprising:(a) immersing a stamp in a solution, wherein the stamp has at least one conductive pathway and at least one insulating layer over the conductive pathway, and wherein the solution comprises molecules each having at least one charged portion; (b) biasing the conductive pathway of the stamp such that the conductive pathway is charged with respect to said solution, and such that portions of the molecules having an opposite charge of the conductive pathway are attracted to the insulating layer by electrostatic attraction in a pattern essentially defined by the pattern of the conductive pathway; (c) removing the stamp from the solution; (d) positioning the stamp over a substrate; and (e) transferring the molecules from the stamp to the substrate.
