  • Publication number: 20210196673
    Abstract: Modified green tea polyphenol compositions and their methods of use in treating and preventing SARS-CoV-2 infections are provided. An exemplary green tea polyphenol composition includes (?)-epigallocatechin-3-gallate that can be esterified with a C1-C30 group in at least one position and a carrier such as glycerol. The modified green tea polyphenol compositions can be used to treat and prevent SARS-CoV-2 infections without coming into contact with the viral cell.

  • Patent number: 7514183
    Abstract: A method of generating a mask for use in a photolithography process. The method includes the steps of determining a target mask pattern having a plurality of features to be imaged and an illumination system to be utilized to image the mask; identifying a critical pitch within the target pattern and optimizing illumination settings of the illumination system for imaging the critical pitch; identifying a forbidden pitch within the target pattern; and modifying the transmittance of the features having a pitch equal to or substantially equal to the forbidden pitch such that the exposure latitude of the features equal to or substantially equal to the forbidden pitch is increased.

  • Patent number: 6915505
    Abstract: A method of printing a gate pattern on a substrate comprising the steps of: identifying at least one area in the pattern in which one of the gate features overlays one of the active regions; reducing a width dimension of the one of the gate features at the location which the one of the gate features overlays the one of the active regions; extracting the gate features from the pattern; decomposing the gate features into a vertical component mask and a horizontal component mask; and illuminating the vertical component mask and the horizontal component mask utilizing dipole illumination.
