Gate length of mosfet
WebMOSFET are the gate length (180 nm), the p–n junction depth (100 nm), and the gate oxide thickness, tox (3–5 nm); the narrowest feature is the gate oxide. Here, we identify the gate oxide as the principal im-pediment to scaling the gate length of nMOSFETs and pMOSFETs to 35 nm, as shown in Fig. 1. The viability of sub-50 nm CMOS technology is WebMOSFETs, can be expressed as the following equation: GS fs ΔV g =ΔIDS CH n OX fs L C W g = ⋅ μ It is usually measured at saturation region with fixed VDS. The transconductance is influenced by gate width (W), channel length (LCH), mobility (μn), and gate capacitance (COX) of the devices. gfs decreases with increasing temperature due to the
