Abstract: A gas mixture method and apparatus of prolonging lifetime of an ion source for generating an ion beam particularly an ion beam containing carbon is proposed here. By mixing the dopant gas and the minor gas together to generate an ion beam, undesired reaction between the gas species and the ion source can be mitigated and thus lifetime of the ion source can be prolonged. Accordingly, quality of ion beam can be maintained.
