    摘要： A tunneling transistor is provided as an effective means for miniaturization of a semiconductor integrated circuit having nonvolatile memory. An insulating layer is disposed on a silicon substrate. A source and a drain are disposed on the insulating layer, with an insulator of a few nanometers in thickness that provides a tunnel barrier being interposed between the source and the drain. A ferroelectric layer that exhibits spontaneous polarization is disposed directly above a region of the source that is adjacent to the insulator. With this construction, when the ferroelectric layer is polarized in a predetermined direction, at least a portion of the region of the source adjacent to the insulator forms a depletion region, with it being possible to vary the amount of current tunneling through the insulator depending on whether the ferroelectric layer is polarized or not.

    摘要： A method for randomizing data to mitigate false VFO detection is described. In one embodiment, such a method includes simultaneously receiving multiple input data streams. Each input data stream is associated with a different track on a magnetic tape medium. The input data streams are simultaneously scrambled to produce multiple randomized data streams. The input data streams are scrambled such that different bit patterns are produced in the randomized data streams even where corresponding bit patterns in the input data streams are identical. The randomized data streams are simultaneously written to their associated data tracks on the magnetic tape medium. A corresponding apparatus is also described.

    摘要： A determination method, a control method, a determination apparatus, a pattern forming system, and a storage medium can determine a replacement time of a focus ring accurately and quickly. The determination method is capable of determining the replacement time of a focus ring that surrounds a substrate to increase uniformity of a pattern in a surface of the substrate when the pattern is formed by etching a film on the substrate. The determination method includes measuring a shape or a critical dimension of the pattern; and determining the replacement time of the focus ring based on the measured shape or the measured critical dimension of the pattern.

    摘要： A method for physically laying out data on tape is disclosed herein. In one embodiment, such a method includes receiving a data set, wherein the data set includes S sub data sets (SDSs) of fixed size and each SDS includes N codeword interleaves (CWIs). The method further distributes the CWIs for the S SDSs across T tracks on a physical tape medium such that the distances between CWIs of the same SDS are substantially maximized on the physical tape medium. To maximize the distances, the method periodically rotates the tracks within the data set by a track rotation value R, wherein the number of tracks T is equal to 2k, and the track rotation value R is equal to 2k−1−1. A corresponding apparatus is also disclosed herein.
