A MOS transistor including a gate electrode on a gate oxide over a channel region between a source region and a drain region also includes a shield electrode at least partially on the gate oxide adjacent to, self-aligned with, and at least partially coplanar with the gate electrode and between the gate electrode and drain region. Placing the shield electrode on the gate oxide improves the gate-drain shielding, reduces the gate-drain capacitance, Cgd, and reduces hot electron related reliability hazard.
