    摘要: A semiconductor device is formed on a substrate having an ESD region and an internal region. A protective layer is formed over a portion of the ESD region to be protected from formation of silicide and silicide is formed on portions of the Internal and ESD region which remain unprotected by the protective layer. A portion of the protective layer is removed to form the remaining portions of the protective layer into sidewall spacers adjacent to a gate electrode included in the ESD region.

    摘要: An ESD protection structure for protecting an internal circuit comprising a primary protection device, a secondary protection device, and a substrate pickup is presented. The primary protection device and secondary protection device share a common source, and this common source implementation lowers the trigger voltage of the primary protection device to be about the same as the trigger voltage of the secondary protection device, thereby eliminating the need to use an isolation resistor between the primary and secondary protection devices.

    摘要: A self-protected output driver for an integrated circuit utilizing cascode configured MOSFET transistors is formed in a single active region, allowing a smaller layout area without sacrificing performance. Furthermore, the driver is laid out according to a standard cell layout and is adaptable for a variety of output driving specifications according to the need of a particular implementation. A doped region having a first conductivity type is formed in the substrate. A plurality of sets of cascode connected transistors having channels in the doped region is included. Sets of cascode connected transistors in the plurality include a first diffusion region, a second diffusion region on a first side of and separated from the first diffusion region by a channel of a first transistor, a third diffusion region on a second side of and separated from the first diffusion region by a channel of the second transistor, a fourth diffusion region on a first side of and separated from the second diffusion region by a channel of a third transistor, a fifth diffusion region on a second side of and separated from the third diffusion region by a channel of a fourth transistor. Gate structures are formed over the channels of the first, second, third and fourth transistors. An interconnect structure couples the first diffusion region to the contact pad, the fourth and fifth diffusion regions to the second supply terminal, the gate structures of the first and second transistors to a first supply terminal, the gate structure of the third transistor to a selected one of the second supply terminal and a signal source, and the gate structure of the fourth transistor to a selected one of the signal source and the second supply terminal. The structure acts typically as a pull-down stage for an output driver on an integrated circuit. A pull-up transistor is included in the complete circuit. The diffusion regions between the first and third transistor and between the second and fourth transistor are formed without silicide.

    摘要: Mask ROMS with fixed code implantation and associated integrated circuits are described. An integrated circuit has a Mask ROM including: an array of memory cells including a first bank of memory cells and a second bank of memory cells, and the first bank of memory cells separated from the second bank of memory cell by a set of select lines, and the first bank of memory cells and the second bank of memory cells includes at least one fixed code implanted memory cell column. The use of fixed code implantation results in a single current path during the reading of a given memory cell and permits the size of the corresponding device to be reduced and have better topography. The Mask ROM provides additional advantages because the use of the same select transistors for two banks reduces the overhead of select transistors for a given size of array, the use of only one sense amplifier per block reduces the overhead of sense amplifiers for a given size of array, and the use of odd and even word line decoders divides the memory cell array into a number of banks.
