Patent ID: 7687863

Claim:
An integrated circuit, comprising: a complementary metal oxide semiconductor device having an NFET and PFET, the NFET device including positively charged dopants at or near a transistor channel for selectively controlling a threshold voltage independently of channel doping and gate workfunction to provide for short channel control of the NFET, the PFET being free of the positively charged dopants, the NFET device including: a gate stack including the positively charged dopants selectively placed into the gate stack using a layer rich in a passivating element which is annealed by an anneal process to drive-in the passivating element to increase a concentration of charge at or near the transistor channel; and a source region and a drain region, which are amorphized during formation, being disposed on opposite sides of the gate stack and including a recrystallized structure formed by the anneal process.
