Abstract:

It was attempted to deposit hard carbon films using the ionized cluster beam deposition method with organic materials. The principle idea was to have the organic molecules to decompose on impact with the substrate. A major problem involved the decomposition of organic starting material in the crucible. It was hoped to use lower crucible temperatures to reduce decomposition. Increased crucible temperatures were eventually used to increase the deposition rate. This resulted in more hydrogen in the chamber and the 50 Is turbomolecular pump was unable to maintain a pressure below about 8 x 10-4 torr. Changes and experiments are being made, but to date the endeavor has been unsuccessful. JS
