Abstract:
1. A method for selective deposition of a deposition material to a deposition surface, comprising the steps of: providing a substrate, said substrate including a deposition surface disposed in an operable thermal relationship with at least one heating source; applying a solvent containing a precursor upon said deposition surface, said precursor miscible in and stable at liquid, near-critical, or supercritical conditions for said solvent, said precursor comprising a deposition material releasable at a preselected release temperature or condition; heating said substrate with said at least one heating source to generate a temperature gradient along said deposition surface; whereby said deposition material is released from said precursor and selectively deposited upon said surface in response to said temperature gradient thereby controlling the location and quantity of said deposition material deposited upon said deposition surface.
