  Multi-bridge channel field effect transistor (MBCFET) provides several
advantages over FinFET technology and is an attractive solution for sub-5 nm
technology nodes. MBCFET is a natural choice for devices that use
semiconducting layered materials (such as, MoS$_2$) as the channel due to their
dangling-bond-free ultra-thin nature and the possibility of layer-by-layer
transfer. MoS$_2$-based MBCFET is thus an attractive proposition for drive
current boost without compromising on the electrostatics and footprint. Here we
demonstrate a 3-level MoS$_2$ MBCFET, where each vertically stacked channel is
dual-gated to achieve a saturation current of 174.9 $\mu$A (which translates to
\txc{90 $\mu$A per $\mu$m footprint width (@2.7 $\mu$m channel length), a
near-ideal sub-threshold slope of 63 mV/dec, and an on-off ratio $>$$10^8$.
This work sets the benchmark for layer-material-based MBCFET in terms of the
number of parallel channels integrated, simultaneously providing high drive
current and excellent electrostatic control.
