Abstract
A solid delivery precursor is described, which is useful for volatilization to generate precursor vapor for a vapor deposition process. The solid delivery precursor comprises solid bodies of compacted particulate precursor, e.g., in a form such as pellets, platelets, tablets, beads, discs, or monoliths. When utilized in a vapor deposition process such as chemical vapor deposition, pulsed chemical vapor deposition, or atomic layer deposition, the solid delivery precursor in the form of solid bodies of compacted particulate precursor provide substantially increased flux of precursor vapor when subjected to volatilization conditions, in relation to the particulate precursor. As a result, vapor deposition process operation can be carried out in shorter periods of time, thereby achieving increased manufacturing rates of products such as semiconductor products, flat-panel displays, solar panels, LEDs, optical coatings, and the like.
