Embodiment Construction
[0021] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] Such as figure 1 as shown, figure 1 It is an SOI-NMOS device that can be used in the present invention. The SOI silicon wafer comprises a top silicon film (1), an insulating oxide layer (2) and a silicon substrate (3), and an SOI-NMOS device is prepared on the top silicon film (1). The SOI material is a commercial conventional oxygen ion implantation isolation (SIMOX) sheet, and other thermal bonding and smart-cut (Smart-Cut) sheets can also be used. For a normal SOI-NMOS device, the gate and drain are connected to the power supply potential (Vdd), and the source and back gate are connected to the ground potential (Vss).
[0023] Bulk silicon NMOS devices in the prior art generally have only three terminals, namely: gate, source and drain, and only focus on the threshold voltage of the gate. The general method for ...
