    摘要: Integrated circuit antifuse circuitry is provided. A metal-oxide-semiconductor (MOS) transistor serves as an electrically-programmable antifuse. The antifuse transistor has source, drain, gate, and substrate terminals. The gate has an associated gate oxide. In its unprogrammed state, the gate oxide is intact and the antifuse has a relatively high resistance. During programming, the gate oxide breaks down, so in its programmed state the antifuse transistor has a relatively low resistance. The antifuse transistor can be programmed by injecting hot carriers into the substrate of the device in the vicinity of the drain. Because there are more hot carriers at the drain than at the substrate, the gate oxide is stressed asymmetrically, which enhances programming efficiency. Feedback can be used to assist in turning the antifuse transistor on to inject the hot carriers.

    摘要: Integrated circuit antifuse circuitry is provided. A metal-oxide-semiconductor (MOS) antifuse transistor serves as an electrically-programmable antifuse. In its unprogrammed state, the antifuse transistor is off and has a relatively high resistance. During programming, the antifuse transistor is turned on which melts the underlying silicon and causes a permanent reduction in the transistor's resistance. A sensing circuit monitors the resistance of the antifuse transistor and supplies a high or low output signal accordingly. The antifuse transistor may be turned on during programming by raising the voltage at its substrate relative to its source. The substrate may be connected to ground through a resistor. The substrate may be biased by causing current to flow through the resistor. Current may be made to flow through the resistor by inducing avalanche breakdown of the drain-substrate junction or by producing Zener breakdown of external Zener diode circuitry connected to the resistor.

    摘要: A new method of local oxidation using a nitrogen implant through a spin-on-glass film is described. A thin silicon oxide layer is formed over the surface of a silicon substrate. A layer of silicon nitride is deposited overlying the silicon oxide layer. The silicon oxide and silicon nitride layers are patterned to provide openings of various sizes exposing portions of the silicon substrate to be oxidized. Ions are selectively implanted into the silicon substrate through the openings. The patterned surface of the substrate is covered with a spin-on-glass material. The spin-on-glass material is thicker within the smaller openings and thinner within the larger openings. The spin-on-glass material is soft-baked. Nitrogen ions are selectively implanted into the silicon substrate through the spin-on-glass material within the openings wherein fewer nitrogen ions are implanted through the thicker spin-on-glass material within the smaller openings and more nitrogen ions are implanted through the thinner spin-on-glass material within the larger openings. The spin-on-glass material is removed. Field oxide regions are grown within the openings wherein the rate of field oxidation is inhibited most within the openings through which a larger concentration of nitrogen ions were implanted and inhibited to a lesser extent in openings through which smaller concentrations of nitrogen ions were implanted resulting in nearly equal thicknesses of field oxide regions in all openings of various sizes.
