  • Patent number: 10570532
    Abstract: The present invention relates to a polyolefin pellet for preparing a fiber, and a fiber comprising the same. According to the present invention, provided is a polyolefin, which exhibits a high molecular weight range and a narrow molecular weight distribution and in which the formation of a gel deteriorating the quality of a fiber is reduced. Therefore, by using the polyolefin pellet, the present invention exhibits a molecular weight, a density and a narrow molecular weight distribution, which are equivalent to those of conventional polyolefin, but has high tenacity and an excellent drawing characteristic and can be highly oriented because gel formation is reduced, and therefore, the present invention can be applied to various industrial products due to a high draw ratio and crystallinity during a multifilament operation using the same.

  • Publication number: 20200058497
    Abstract: Embodiments described herein relate to methods of controlling the uniformity of SiN films deposited over large substrates. When the precursor gas or gas mixture in the chamber is energized by applying radio frequency (RF) power to the chamber, the RF current flowing through the plasma generates a standing wave effect (SWE) in an inter-electrode gap. SWEs become significant as substrate or electrode size approaches the RF wavelength. Process parameters, such as process power, process pressure, electrode spacing, and gas flow ratios all affect the SWE. These parameters can be altered in order to minimize the SWE problem and to achieve acceptable thickness and properties uniformities. In some embodiments, methods of depositing a dielectric film over a large substrate at various process power ranges, at various process pressure ranges, at various gas flow rates, while achieving various plasma densities will act to reduce the SWE, creating greater plasma stability.
