Abstract
High performance digital transistors ( ) and analog transistors ( ) are formed at the same time. The digital transistors ( ) include pocket regions ( ) for optimum performance. These pocket regions ( ) are partially or completely suppressed from at least the drain side of the analog transistors ( ) to provide a flat channel doping profile on the drain side. The flat channel doping profile provides high early voltage and higher gain. The suppression is accomplished by using the HVLDD implants for the analog transistors ( ).
