    • Methods are provided for significantly reducing electron trapping in semiconductor devices having a floating gate and an overlying dielectric layer. The methods form a nitrogen-rich region within the floating gate near the interface to an overlying dielectric layer. The methods include selectively introducing nitrogen into the floating gate prior to forming the overlying dielectric layer. This forms an initial nitrogen concentration profile within the floating gate. An initial portion of the overlying dielectric layer is then formed of a high temperature oxide (HTO). The temperature within the floating gate is purposely raised to an adequately high temperature to cause the initial nitrogen concentration profile to change due to the migration of the majority of the nitrogen towards the interface with the overlying dielectric layer and an interface with an underlying layer. Consequently, the floating gate is left with a first nitrogen-rich region near the interface to the overlying dielectric layer and a second nitrogen-rich region near the interface to the underlying layer. The first nitrogen-rich region has been found to reduce electron trapping within the floating gate, which could lead to false programming of the floating gate. Unlike a conventional thermally grown oxide film, the high temperature oxide film within the interpoly dielectric layer advantageously prevents the surface of the floating gate from becoming too granular. As such, the resulting interpoly dielectric layer, which typically includes several films, can be formed more evenly.
    • 提供了用于显着减少具有浮置栅极和上覆电介质层的半导体器件中的电子俘获的方法。 该方法在与上覆电介质层的界面附近的浮栅内形成富氮区。 所述方法包括在形成上覆电介质层之前将氮气选择性地引入浮栅。 这在浮动栅极内形成初始氮浓度分布。 然后由上覆电介质层的初始部分由高温氧化物(HTO)形成。 浮置栅极内的温度有意地升高到足够高的温度,以使得初始氮浓度分布由于大部分氮向与上覆介质层的界面的迁移以及与下层的界面而改变。 因此,浮置栅极在与上覆电介质层的界面附近的第一富氮区域和与下层的界面附近的第二富氮区域留下。 已经发现第一个富氮区域减少了浮动栅极内的电子俘获,这可能导致浮动栅极的错误编程。 与传统的热生长氧化膜不同,多聚电介质层内的高温氧化膜有利地防止浮栅的表面变得太细。 因此,可以更均匀地形成通常包括几个膜的所得到的互间介电层。

    • A sensor apparatus and electrode configuration within the sensor apparatus for measuring electrical characteristics of an aqueous fibrous composition. The electrode configuration includes an elongated ground electrode and at least one segmented electrode to form an array of measurement electrode cells. The electrode configuration further includes an array of reference electrode cells formed by a plurality of reference electrodes built into the array of measurement electrode cells. The measurement electrode cells and reference electrode cells have a different sensitivity to water weight of the aqueous fibrous composition and the same sensitivity to conductivity of the aqueous fibrous composition. The measurement apparatus obtains simultaneous resistive measurements from both measurement and reference cells and determines the ratio of the measurements such that the affects from conductivity is canceled out of the measurement ratio. The determined measurement ratio is used to obtain a measurement of the water weight of the aqueous fibrous composition by using previously determined characterization data of the water weight vs. a range of measurement ratios.

    • The present invention relates to an isolated naturally-occurring soluble truncated IL-23Rα protein, which is a translated protein resulting from a mRNA splice variant of IL-23Rα. The soluble IL-23Rα proteins (e.g., Δ9 and Δ8,9) represents a novel soluble IL-23Rα protein, which is lacking a transmembrane domain and has a unique eight (8) amino acids (GLKEGSYC) at its C-terminus end (due to frame-shift). ELISA reveals that Δ9 is present in blood and can serve as a diagnostic tool for auto-immune diseases including Crohn's disease. There is also provided a method of recombinant production for this soluble truncated form of IL-23Rα protein. More importantly, the present invention provides an utility application of the Δ9 and Δ8,9 protein in inhibit IL-23R-mediated cell signaling. More particularly, Δ9 and Δ8,9 blocks STAT3 formation as well as Th17 maturation. There is provided a therapeutic application of Δ9 and Δ8,9 in treating a human patient inflicted with Crohn's disease.
