Abstract :
The D-source, which ensures beam current increase in the LEX series, SEN´s high current batch-type implanter, has been developed for productivity improvement or COO reduction. The D-source can achieve beam current increase dramatically only by replacing the original source. Moreover, the D-source has longer source life time with easier maintenance. Performance of the D-source was reported in this paper.
