  • Patent number: 10718083
    Abstract: A method for controlling a laundry processing apparatus, according to an embodiment of the present invention, is a method for controlling a clothes processing apparatus, comprising the steps of: inputting a “drying” start command; forwardly rotating a drying drum and a drying fan; supplying hot air into the drying drum; operating a timer so as to calculate drying time; and operating a dryness sensor so as to detect the dryness of laundry, wherein a controller determines that the laundry is tangled, if a dryness sensing value (K) detected by the dryness sensor is greater than or equal to a first set value (k1) before a first set time (T1) elapses after “drying” starts, and the controller performs a primary laundry untangling process for reversely rotating the drying drum for a second set time (T2).

  • Publication number: 20200194251
    Abstract: Embodiments described herein generally relate to conformal oxidation processes for flash memory devices. In conventional oxidation processes for gate structures, growth rates have become too fast, ultimately creating non-conformal films. To create a preferred growth rate for SiO2 on SiNx films, embodiments in this disclosure use a thermal combustion of a ternary mixture of H2+O2+N2O to gain SiO2 out of Si containing compounds. Using this mixture provides a lower growth in comparison with using only H2 and O2, resulting in a lower sticking coefficient. The lower sticking coefficient allows an optimal amount of atoms to reach the bottom of the gate, improving the conformality in 3D NAND SiO2 oxidation layers, specifically for ONO replacement tunneling gate formation.
