Vt Model Formulation: RSCE (Vt Roll-Up) and Leff Model
Channel doping (Nch) is replaced by Neff to include the 2D boron pileup (Npile) with lateral spread (lb), modulated by an Leff-dependent function. The Npile-to-Nch ratio (k) assumes a linear Vbs dependence
- New Neff formulation — two lateral Gaussian-shaped pileup profiles
Fitting parameters: b, k0 and k1
