Ion implantation device and a method of semiconductor manufacturing by the implantation of boron hydride cluster ions

Abstract

An ion implantation device and a method of manufacturing a semiconductor device is described, wherein ionized boron hydride molecular clusters are implanted to form P-type transistor structures. For example, in the fabrication of Complementary Metal-Oxide Semiconductor (CMOS) devices, the clusters are implanted to provide P-type doping for Source and Drain structures and for Polygates; these doping steps are critical to the formation of PMOS transistors. The molecular cluster ions have the chemical form BnHx+ and BnHx−, where 10≦n≦100 and 0≦x≦n+4.
