MST - Variability

MST Makes Transistors More Predictable and Reliable

MST Reduces Variability

  • By confining the doping to a peak away from the interface, MST can be used to reduce one of the major sources of variability in semiconductor devices known as random dopant fluctuation, while maintaining the threshold voltage
  • This figure is from a recent publication with one of our analog partners and shows >50% Avt reduction (a measure of the variability reduction). Look at this blog post for added discussion.
