Air Spacer MOSFET Technology for 20nm Node and Beyond
Two types of air spacer technologies are proposed and TCAD simulation is used to construct 20nm-gate transistor.One is non-SAC (Self Aligned Contact) process with air spacer. It is compared with nitride-spacer and oxide-spacer transistors representing the two extremes of conventional spacer technologies.With 10nm air spacers, the CMOS inverter delay is reduced by 45% and 30% compared to the nitride-spacer and oxide-spacer technologies respectively.Furthermore, the switching energy (power consumption) is reduced by 46% and 33% respectively. The other is SAC process with air spacer.3D mixed mode simulation shows that the 35% area benefit can be retained while improving the speed and switching energy by 75% to be 10% better than a non-SAC device.
