发明名称 Self-aligned silicide for word lines and contacts
摘要 An embodiment of a floating-gate memory cell has a tunnel dielectric layer formed overlying a semiconductor substrate; a drain region formed in a semiconductor substrate adjacent a first side of the tunnel dielectric layer, a source region formed in a semiconductor substrate adjacent a second side of the tunnel dielectric layer, a floating-gate layer formed overlying the tunnel dielectric layer, a control-gate layer formed overlying the floating-gate layer, and an intergate dielectric layer formed interposed between the floating-gate layer and the control gate layer. The control-gate layer includes a silicide layer in contact with an underlying polysilicon layer. There is no interposing dielectric layer between the control-gate layer and an overlying bulk insulator layer, and a width of the silicide layer is substantially equal to a width of the polysilicon layer.
