- Abstract
- An analytic and continuous direct-current model for cylindrical doped surrounding-gate metal-oxide-semiconductor field-effect transistors (SGMOSFETs) including interface-trap charges is presented. Based on the SGMOSFET model, which is valid from undoped to heavily doped channels, a general model for long-channel SGMOSFETs including interface-trap charges is derived. A comparison between the numerical simulations and analytic calculations showed that the proposed model is valid for all operating regions of SGMOSFETs including different interface-trap charges with several dimensions and doping densities.
