Impact of Parameter Variations and Random Dopant Fluctuations on Short-Channel Fully Depleted SOI MOSFETs With Extremely Thin BOX

Characteristic variations of fully depleted silicon-on-insulator (SOI) MOSFETs with extremely thin buried oxide are examined by device simulations. It is found, for the first time, that a SOI device with low channel impurity concentration and high substrate concentration has high immunity to both parameter variations and random dopant fluctuations (RDFs). Fully depleted (FD) silicon-on-insulator (SOI) MOSFET, random dopant fluctuation (RDF), thin buried oxide (BOX), variability.
