Abstract
PURPOSE:To decrease a pulse current value required for cutting bubbles by cutting the bubbles between the ion implantation system transfer paths of a gate circuit on the border of the transfer path. CONSTITUTION:The hair pin part of a conductor 40 is extended along the border of a closed loop-shaped ion implantation transfer path 30 and arranged so as to cross a bridged bubble b1, and the cutting position of the bubble b1 is arranged at a point D on the border of the transfer path 30. Further, intervals l between transfer paths 20 and 30 are arranged to be short and reduced to be 1.5 to 4 times to a bubble diameter. At first, a bubble (b) transferred to an A point is extended along the border of the transfer path 30 and further extended to a point B on the other transfer path 20 so as to make the string- shaped bubble b1. Next, the bubble b1 is cut at the border point D by the flow of the pulse current to the conductor and two bubbles b2 and b3 are made. Since the bubble is cut on the closed loop-shaped transfer path border, the smaller pulse current value is enough.
