摘要
Analytical formulas associated with threshold voltage fluctuations in metal-oxide-semiconductor field-effect-transistors (MOSFETs) are systematically derived under the quasi one-dimensional approximation. The derivation of the formula for the threshold voltage variance clearly shows the approximations involved so that the limitation of the formula is clarified. Also, analytical expressions of the local threshold voltage probability distributions in the Substrate of MOSFETs, which give the detailed information of the microscopic distributions of the threshold voltage fluctuations, are derived.
