EUROSOI VIRTUAL JOURNALTitle: Dual-Material Double-Gate SOI n-MOSFET: Gate Misalignment Analysis
Autors: Sharma RK, Gupta R, Gupta M, Gupta RSTHEME: Device physics, modelling and simulation Publication: IEEE TRANSACTIONS ON ELECTRON DEVICES YEAR: 2009 MONTH: JUN ISI Document Solution number: 449KT 10.1109/TED.2009.2019695 ABSTRACT: The dual-material double-gate (DMDG) silicon-on-insulator (SOI) metal-oxide-semiconductor field-effect transistor (MOSFET) is the leading contender for sub-100-nm devices because it utilizes the benefits of both double-gate and dual-material-gate structures. One major issue of concern in the DMDG-MOSFET is the alignment between the top and the bottom gate that critically influences the device performance. In this paper, we have investigated the effects of gate misalignment in the DMDG SOI n-MOSFET. In this regard, analytical modeling and extensive simulations have been carried out to analyze the gate misalignment effects on device performance like surface potential, electric field, threshold voltage, subthreshold slope, drain-induced barrier lowering, drain current, and transconductance. Considering the fact that gate misalignment can occur on any side of the gate, both source- and drain-side misalignments have been discussed. Analytical and simulated results are found to be in good agreement, which authenticate our proposed model for the DMDG structure.
