    摘要: A zero threshold voltage (ZVt) pFET (104) and a method of making the same. The ZVt pFET is made by implanting a p-type substrate (112) with a retrograde n-well (116) so that a pocket (136) of the p-type substrate material remains adjacent the surface of the substrate. This is accomplished using an n-well mask (168) having a pocket-masking region (184) in the aperture (180) corresponding to the ZVt pFET. The n-well may be formed by first creating a ring-shaped precursor n-well (116′) and then annealing the substrate so as to cause the regions of the lower portion (140′) of the precursor n-well to merge with one another to isolate the pocket of p-type substrate material. After the n-well and isolated pocket of p-type substrate material have been formed, remaining structures of the ZVt pFET may be formed, such as a gate insulator (128), gate (132), source (120), and drain (124).

    摘要: A detector circuit and method for detecting a silicon well voltage or current to indicate an alpha particle or cosmic ray strike of the silicon well. One significant application for the detection circuit of the present invention is for the redundancy repair latches that are used in SRAMs. The redundancy repair latches are normally written once at power-up to record failed latch data and are not normally written again. If one of the latches changes states due to an SER (Soft Error Rate-such as a strike by an alpha particle or cosmic ray) event, the repair data in the redundancy latches of the SRAM would now be incorrectly mapped. The detector circuit and method monitors the latches for the occurrence of an SER event, and responsive thereto issues a reload of the repair data to the redundancy repair latches. A first embodiment of the detector circuit differentially detects the floating voltages of first and second silicon wells during periods of non-operation of the circuits fabricated in the first and second silicon wells. In a second embodiment, a detector circuit monitors the background voltage level of a single silicon well over first and second consecutive periods of time. A second application for the detection circuit is for traditional logic circuits.

    摘要: The present invention provides a method of forming an ultra-thin and uniform layer of Si including the steps of providing a substrate having semiconducting regions separated by insulating regions; implanting dopants into the substrate to provide an etch differential doped portion in the semiconducting regions underlying an upper Si-containing surface of the semiconducting regions; forming a trench in the substrate including the semiconducting regions and the insulating regions; removing the etch differential doped portion from the semiconductor regions to produce a cavity underlying the upper surface of the semiconducting regions; and filling the trench with a trench dielectric, wherein the trench dielectric material encloses the cavity underlying the upper Si-containing surface of the semiconducting regions. The upper Si-containing surface of the semiconducting regions has a uniform thickness of less than about 100 Å.

    摘要: A selectively silicided semiconductor structure and a method for fabricating same is disclosed herein. The semiconductor structure has silicide present on the polysilicon line between the N+ diffusion or N+ active area and the P+ diffusion or active area at the N+/P+ junction of the polysilicon line, and silicide is not present on the N+ active area and the P+ active area. The presence of this selective silicidation creates a beneficial low-resistance connection between the N+ region of the polysilicon line and the P+ region of the polysilicon line. The absence of silicidation on the N+ and P+ active areas, specifically on the PFET and NFET structures, prevents current leakage associated with the silicidation of devices.

    摘要: Methods of fabricating an integrated circuit with a fin-based fuse, and the resulting integrated circuit with a fin-based fuse are provided. In the method, a fin is created from a layer of semiconductor material and has a first end and a second end. The method provides for forming a conductive path on the fin from its first end to its second end.
