1. A semiconductor structure, comprising:
a first region having a first conductivity type and having a sidewall;
a second region having a second conductivity type, wherein the second conductivity type is different than the first conductivity type;
an active area sidewall spacer adjacent the sidewall of the first region, wherein the active area sidewall spacer comprises an insulating layer;
a gate dielectric overlying at least a portion of the first region and at least a portion of the active area sidewall spacer;
a gate electrode overlying the gate dielectric; and
a second insulating layer, wherein each of the first region, the second region, and the active area sidewall spacer is on and in physical contact with the second insulating layer.
