Abstract: In some embodiments, the present disclosure relates to a semiconductor device comprising a source and drain region arranged within a substrate. A conductive gate is disposed over a doped region of the substrate. A gate dielectric layer is disposed between the source region and the drain region and separates the conductive gate from the doped region. A bottommost surface of the gate dielectric layer is below a topmost surface of the substrate. First and second sidewall spacers are arranged along first and second sides of the conductive gate, respectively. An inner portion of the first sidewall spacer and an inner portion of the second sidewall spacer respectively cover a first and second top surface of the gate dielectric layer. A drain extension region and a source extension region respectively separate the drain region and the source region from the gate dielectric layer.

Abstract: A surveillance method, a surveillance apparatus, and a marking module are applied to an active burglarproof system. The surveillance method includes the following steps. Determine whether a first wireless signal related to a marking module is received in a first sensing region, to produce a first determination result. Determine whether the first wireless signal is received in a second sensing region, to produce a second determination result. Selectively generate a warning signal according to the first determination result and the second determination result.
