What is LDD structure?
Short for lightly doped drain. The drain is made lightly doped only at its edge next to the gate, relaxing the electric field and suppressing hot-carrier degradation.
Field: MOSFET
LDD structure in the explanations
An LDD structure uses the gate sidewall spacer to form a shallow, lightly doped region on the channel side of the drain, lowering the peak field and suppressing degradation.
