Abstract
The investigation of the Dual-k spacer through comparative analysis of single nanowire-FET(NWFET)/3-stack NWFET and underlap/overlap channel is conducted. It is known that the dug 3-stack NWFET has better delay characteristics than single NWFET with the use of high permittivity material of Cin in Dual-k spacer structure. In addition, there is no difference of delay between overlap and underlap channel when it used Dual-k spacer structure but underlap channel of Dual-k 3-stack NWFET shows better short channel immunity.
