Abstract
Provided herein are improved methods of depositing carbon-based films using acetylene as a precursor. The methods involve using a low-vapor pressure solvent, e.g., dimethylfluoride (DMF) to stabilize the acetylene and delivering the acetylene to a deposition chamber. The methods provide improved wafer-to-wafer thickness uniformity and increase the usable amount of acetylene in an acetylene source to over 95%.
