Un-Passivated Device

tftex02.in : Un-Passivated Device

Requires: S-Pisces/TFT
Minimum Versions: Atlas 5.24.1.R

This file performs Id/Vgs simulation of a TFT device with material properties corresponding to un-passivated alpha-Si:H material. The example shows:

  • Structure formation using Atlas syntax
  • Material and model settings for un-passivated a-Si
  • Forward Id/Vgs characteristics

The key command in TFT simulation is the defect statement. It is used to define a continuous density of trap states in the silicon and the relevant trapping cross-sections.

The Id/Vgs ramping is performed in a similar manner to the threshold voltage tests for MOS devices described in the MOS example. Results from this example can be compared with the passivated a-Si device.

A more detailed description of TFT material settings is given in the Forward/Reverse Gate Voltage Characteristic example.
