Original Abstract

As the NMOSFET channel length continues to shrink and so does the gate oxide thickness, the dominant component of the leakage current through the gate oxide becomes the charge-carrier direct tunneling from the channel and source-drain extensions into the polygate. The contribution deals with TCAD simulation of this tunneling current in the NMOSFET structures with gate oxide thicknesses below 20 A. The 2D NMOS transistor structure is generated using ISE TCAD tools DIOS and MDRAW. DESSIS simulates gate leakage current due to direct electron tunneling through the gate oxide and INSPECT generates and compares I-V plots for 7 different simulation runs. The individual simulations are run under GENESISe.
