  • Patent number: 7728396
    Abstract: A method and a structure are provided for preventing lift-off of a semiconductor monitor pattern from a substrate. A semiconductor structure and a semiconductor monitor structure are formed on a substrate. A material layer is formed covering the semiconductor monitor structure. A part of the semiconductor structure is removed without removing the semiconductor monitor structure, by using the material layer as an etch protection layer. A mask for the method is also provided. The mask includes a clear area and a dark area. The dark area prevents a semiconductor monitor structure from being subjected to exposure so as to form a material layer covering the semiconductor monitor structure and prevent removal of the semiconductor monitor structure from the substrate while a part of a semiconductor structure is removed.

    Abstract: A method for operating a one-time programmable read-only memory (OTP-ROM) is provided. The OTP-ROM comprises a first gate and a second gate respectively disposed on a gate dielectric layer between a first doped region and a second doped region on a substrate, wherein the first gate is adjacent to the first doped region and coupled to the first doped region, the second gate is adjacent to the second doped region, the first gate is electrically coupled grounded, and the OTP-ROM is programmed through a breakdown effect. The method comprises a step of programming the OTP-ROM under the conditions that a voltage of the second doped region is higher than a voltage of the first doped region, the voltage of the second gate is higher than a threshold voltage to pass the voltage of the second doped region, and the first doped region and the substrate are at a reference voltage.
