At equilibrium, the dispersion in the good region of a DPD is a "5" whereas it is usually a "1" in the bridging and depletion regions.
Fully depleted means that the top silicon is thinner (50nm or less) than the depletion width beneath the channel and the depletion region extends to the buried oxide.
