Reduction of dopant loss in a gate structure
A semiconductor device includes offset spacers that contact opposing side surfaces of a gate of a gate structure. The offset spacers can be formed by selectively depositing an oxide layer over the gate and the semiconductor substrate so that the opposing side surfaces of the gate e are substantially free of the oxide layer. Offset spacers can then be formed that contact the opposing side surfaces of the gate.
