    摘要: A semiconductor device includes a transistor, a capacitor and a resistor wherein the capacitor includes a doped polysilicon layer to function as a bottom conductive layer with a salicide block (SAB) layer as a dielectric layer covered by a Ti/TiN layer as a top conductive layer thus constituting a single polysilicon layer metal-insulator-polysilicon (MIP) structure. While the high sheet rho resistor is also formed on the same single polysilicon layer with differential doping of the polysilicon layer.

    摘要: This invention discloses a one-time programmable (OTP) memory cell. The OTP memory cell includes a dielectric layer disposed between two conductive polysilicon segments wherein the dielectric layer is ready to change from a non-conductive state to a conductive state through an induced voltage breakdown. In a preferred embodiment, one of the conductive polysilicon segments further includes an etch undercut configuration for conveniently inducing the voltage breakdown in the dielectric layer. In a preferred embodiment, the dielectric layer is further formed as sidewalls covering the edges and corners of a first polysilicon segments to conveniently induce a voltage breakdown in the dielectric layer by the edge and corner electrical field effects.
