Abstract
An integrated circuit CMOS structure and method for forming the structure provides gate sidewall spacers which are independently optimized for the n-channel and p-channel devices to improve hot-carrier lifetime while maintaining high drive currents. This is accomplished by providing polysilicon spacers for the n-channel devices and silicon nitride spacers for the p-channel devices.
