  • Publication number: 20230420452
    Abstract: Embodiments include a FinFET transistor including an embedded resistor disposed in the fin between the source epitaxial region and the source contact. A control contact may be used to bias the embedded resistor, thereby changing the resistivity of the resistor. Edge gates of the FinFET transistor may be replaced with insulating structures. Multiple ones of the FinFET/embedded resistor combination may be utilized together in a common drain/common source contact design.

  • Publication number: 20230317714
    Abstract: A method includes: forming a fin protruding from a substrate; implanting an n-type dopant in the fin to form an n-type channel region; implanting a p-type dopant in the fin to form a p-type channel region adjacent the n-type channel region; forming a first gate structure over the n-type channel region and a second gate structure over the p-type channel region; forming a first epitaxial region in the fin adjacent a first side of the first gate structure; forming a second epitaxial region in the fin adjacent a second side of the first gate structure and adjacent a first side of the second gate structure; and forming a third epitaxial region in the fin adjacent a second side of the second gate structure.

  • Patent number: 6483751
    Abstract: A pre-erase/incremented erase mechanism is employed to reduce excessive tunnel oxide fields in flash memory cells. A variable conditioning signal removes charge from “fast” bits in the array, so that they are configured to have threshold voltages closer to an ideal initial state in preparation for an erase cycle. In this manner, the voltage thresholds are tightened and equalized, so that over-erasure problems associated with Fowler-Nordheim tunneling erase operations are substantially reduced, and endurance cycles for the array are maximized. The invention can be used in a device in the field, or as part of a design process for a flash memory cell to evaluate device performance.

  • Patent number: 6166962
    Abstract: A novel cell conditioning mechanism is employed to equalize charge discharge characteristics of flash memory cells. A variable conditioning signal removes charge from "fast" bits in the array, and leaves other cells relatively unaffected so that the fast bits are adjusted to have threshold voltages closer to those of the other cells in an array. In this manner, the voltage thresholds are tightened and equalized, so that over-erasure problems associated with Fowler-Nordheim tunneling erase operations are substantially reduced, and endurance cycles for the array are maximized. The invention can be used in a device in the field, or as part of a design process for a flash memory cell to evaluate device performance.
