Reducing the dielectric constant of a portion of a gate dielectric
摘要:
In a metal gate replacement process, a cup-shaped gate metal oxide dielectric may have a vertical portion that may be exposed to a silicon ion implantation. As a result of the implantation, the dielectric constant of a vertical portion may be reduced, reducing fringe capacitance.
