| 20080233280 | Method to form a pattern of functional material on a substrate by treating a surface of a stamp - The invention provides a method to form a pattern of functional material on a substrate. The method uses an elastomeric stamp having a relief structure with a raised surface and having a modulus of elasticity of at least 10 MegaPascal. At least the raised surface of the stamp is treated by exposing the stamp to heat, radiation, electrons, a stream of charged gas, chemical fluids, chemical vapors, and combinations thereof, to enhance wettability of the surface. A composition of the functional material and a liquid is applied to the relief structure and the liquid is removed to form a film on the raised surface. The elastomeric stamp transfers the functional material from the raised surface to the substrate to form a pattern of the functional material on the substrate. The method is suitable for the fabrication of microcircuitry for electronic devices and components. | 09-25-2008 |
