In this paper, the 65-nm node SOI devices with high-k offset spacer was investigated. Calculated results show that the high-k offset spacer can effectively increase Ion and reduce Ioff due to the high vertical fringing field effect arising from the side capacitor comprising of gate/offset spacer/drain extension structure. This fringing field and, in turn, the Ion/Ioff current ratio and subthreshold swing can be strongly enhanced by increasing the dielectric constant of the offset spacer.
