Abstract
A method of implanting carbon ions into a target substrate, including: ionizing a carbon containing dopant material to produce a plasma having ions; optionally co-flowing an additional gas or series of gases with the carbon-containing dopant material; and implanting the ions into the target substrate. The carbon-containing dopant material is of the formula CwFxOyHz wherein if w=1, then x>0 and y and z can take any value, and wherein if w>1 then x or y is >0, and z can take any value. Such method significantly improves the efficiency of an ion implanter tool, in relation to the use of carbon source gases such as carbon monoxide or carbon dioxide.
