Abstract
A liquid injector is used to vaporize and inject a silicon precursor into a process chamber to form silicon-containing layers during a semiconductor fabrication process. The injector is connected to a source of silicon precursor, which preferably comprises liquid trisilane in a mixture with one or more dopant precursors. The mixture is metered as a liquid and delivered to the injector, where it is then vaporized and injected into the process chamber.
