摘要:
A chemical vapor deposition (CVD) method for depositing a thin film on a surface of a substrate is described. The CVD method comprises disposing a substrate on a substrate holder in a process chamber, and introducing a process gas to the process chamber, wherein the process gas comprises a chemical precursor. The process gas is exposed to a non-ionizing heat source separate from the substrate holder to cause decomposition of the chemical precursor. A thin film is deposited upon the substrate.
