i want to know the physics behind the reverse narrow width/channel effect

Re: threshold voltage

The narrow width effect comes from STI isolation. The sharp corners formed by STI create a high electric field that leads to the formation of inversion charges; hence a lower voltage is needed to form the channel leading to a lower threshold voltage
