The threshold voltage of a MOSFET is usually defined as the gate voltage where an inversion layer forms at the interface between the insulating layer (oxide) and the substrate (body) of the transistor. The purpose of the inversion layer's forming is to allow the flow of electrons through the gate-source junction. The voltage of oxide is given by

side. These charges are generated by ions came in the process of deposition of oxide layer. When the charges exist in between the substrate and interface, the value of Vfb and C-V curve will shift by amount of the charge divided by Cox of Ci. The amount of shifting decreases as the position of fiexed charges is far from in
