Claim 12:
13. The method for fabricating a semiconductor device according to claim 12, wherein forming a conductive layer on a side of the insulating layer facing away from the substrate comprises:
forming a polysilicon layer on the side of the insulating layer facing away from the substrate; and
forming a first conductive layer by performing P-type ion doping on a part of the polysilicon layer, and forming a second conductive layer by performing N-type ion doping on a part of the polysilicon layer, the first conductive layer and the second conductive layer constituting the conductive layer;
wherein an orthographic projection of the first conductive layer on the substrate is positioned on an orthographic projection of the first semiconductor structure on the substrate, and the orthographic projection of the first conductive layer on the substrate at least partially overlapping the orthographic projection of the PN junction on the substrate; and
wherein an orthographic projection of the second conductive layer on the substrate is positioned on an orthographic projection of the second semiconductor structure on the substrate, and the orthographic projection of the second conductive layer on the substrate at least partially overlapping the orthographic projection of the PN junction on the substrate.
