The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a device used to amplify or switch electronic signals. It is by far the most common field-effect transistor in both digital and analog circuits. The MOSFET is composed of a channel of n-type or p-type semiconductor material (see article on semiconductor devices), and is accordingly called an NMOSFET or a PMOSFET (also commonly nMOSFET, pMOSFET).

MOSFet tool simulates the current-voltage characteristics for bulk and SOI Field Effect Transistors (FETs) for a variety of different device sizes, geometries, temperature and doping profiles.

Teachnig Material and Exercises:

MOSFET Operation Description

MOSFET Exercise: Long channel vs. short channel device

SOI Exercise: Basic Operation of n-channel SOI Device

Upgrades with subsequent versions:

  1. 8.5: Minor fix regarding the display of 1D plots for the Final Bias.
  2. 8.4: Minor fix regarding the display of 1D plots.
  3. 8.3: Increased the axes limit for 1D plots.
  4. 8.2: Increased Lc (Lsd) limit to 100 um.
  5. 8.1: Fixed minor bug for SOI-MOSFET simulations.
  6. 8: Fixed for oxide dielectric constant (was redundant parameter before).
  7. 6: Added Surface Charge-Vg plot for NMOS and PMOS.
  8. 5: Improved meshing for Imapct Ionization simulations.
  9. 4: Fixed axes units. Added option for Energy balance transport
  10. 3.1: Added status bar for running simulation.
  11. 3: Dynamic contour plot replaces static MATLAB-driver contour plot. This feature fulfills this wish
