Abstract
A method for providing a precursor to a supercritical processing chamber is provided. The precursor in solid form is provided in an ampoule external to the supercritical processing chamber. A fluid is provided to the ampoule, where at least a portion of the gas enters the solid precursor causing a melting point of the precursor to be depressed and thereby causing the solid precursor to melt. The melted precursor is delivered to the supercritical process chamber.
