    Abstract: Methods and apparatuses for reducing roughness using integrated atomic layer deposition (ALD) and etch processes are described herein. In some implementations, after a mask is provided on a substrate, methods include depositing a conformal layer on the mask by ALD to reduce roughness and etching a layer underlying the mask to form patterned features having a reduced roughness. In some implementations, after a substrate is etched to a first depth to form features at the first depth in the substrate, methods include depositing a conformal layer by ALD on sidewalls of the features to protect sidewalls and reduce roughness during a subsequent etch process. The ALD and etch processes may be performed in a plasma chamber.

  • Patent number: 11165537
    Abstract: Embodiments of this application provide a method for encoding data in a wireless communication network. A communication device obtains an information bit sequence of a bit length K and a code length M. When M is greater than or equal to a first threshold and K is greater than or equal to a second threshold, the device divides the information bit sequence into p subsequences that are of an equal length K1. Then the device encodes each of the p subsequence to obtain p encoded subsequences. The device rate-matches each of the p encoded subsequences to obtain p rate matched subsequences, concatenates the p rate matched subsequences to obtain the output sequence of the code length M, then outputs the output sequence.

  • Publication number: 20210287909
    Abstract: A plasma processing system includes a chamber having a coil disposed above a dielectric window for providing radio frequency power to the processing region. An etch gas delivery system is coupled to gas sources used for a first etch of a material. A liquid delivery system includes a source of liquid precursor, a liquid flow controller, and a vaporizer. A controller activates the etch gas delivery system to perform the first etch and activates the liquid delivery system to perform an atomic layer passivation (ALP) process after the first etch to coat features with a conformal film of passivation. Each time the ALP process is completed a single atomic monolayer of the conformal film of passivation is formed. The controller activates the etch gas delivery system to perform a second etch, with the conformal film of passivation protecting the mask and sidewalls of the features during the second etch.
