Leakage increases exponentially as the thickness of the insulating region decreases. Tunneling leakage can also occur across semiconductor junctions between heavily doped P-type and N-type semiconductors.

WebOct 23, 2024 · But controlling the leakage current is not possible because it is far away from the gate interface. The off-current goes up and the subthreshold slope degrades, making it difficult to turn off the transistor. Removing the leakage current is a means for improving electrostatic control. One way of doing it is by employing a multiple-gate structure.
