    摘要: A non-volatile storage system in which a sidewall insulating layer of a floating gate is significantly thinner than a thickness of a bottom insulating layer, and in which raised source/drain regions are provided. During programming or erasing, tunneling occurs predominantly via the sidewall insulating layer and the raised source/drain regions instead of via the bottom insulating layer. The floating gate may have a uniform width or an inverted T shape. The raised source/drain regions may be epitaxially grown from the substrate, and may include a doped region above an undoped region so that the channel length is effectively extended from beneath the floating gate and up into the undoped regions, so that short channel effects are reduced. The ratio of the thicknesses of the sidewall insulating layer to the bottom insulating layer may be about 0.3 to 0.67.

    摘要: Floating gate structures are disclosed that have a projection that extends away from the surface of a substrate. This projection may provide the floating gate with increased surface area for coupling the floating gate and the control gate. In one embodiment, the word line extends downwards on each side of the floating gate to shield adjacent floating gates in the same string. In another embodiment, a process for fabricating floating gates with projections is disclosed. The projection may be formed so that it is self-aligned to the rest of the floating gate.

    摘要: This invention generally relates to liquid phase oxidation processes for making N-(phosphonomethyl)glycine (also known in the agricultural chemical industry as glyphosate) and related compounds. This invention, for example, particularly relates to processes wherein an N-(phosphonomethyl)iminodiacetic acid (NPMIDA) substrate (i.e., N-(phosphonomethyl)iminodiacetic acid, a salt of N-(phosphonomethyl)iminodiacetic acid, or an ester of N-(phosphonomethyl)iminodiacetic acid) is continuously oxidized to form an N-(phosphonomethyl)glycine product (i.e., N-(phosphonomethyl)glycine, a salt of N-(phosphonomethyl)glycine, or an ester of N-(phosphonomethyl)glycine). This invention also, for example, particularly relates to processes wherein an N-(phosphonomethyl)iminodiacetic acid substrate is oxidized to form an N-(phosphonomethyl)glycine product, which, in turn, is crystallized (at least in part) in an adiabatic crystallizer.

    摘要: A string of nonvolatile memory cells connected in series includes fixed charges located between floating gates and the underlying substrate surface. Such a fixed charge affects distribution of charge carriers in an underlying portion of the substrate and thus affects threshold voltage of a device. A fixed charge layer may extend over source/drain regions also.
