  • Publication number: 20220375762
    Abstract: The embodiments of the present disclosure provide an etching method, an air-gap dielectric layer, and a dynamic random-access memory. The etching method is configured to selectively etch a silicon oxide film on a wafer surface that includes the silicon oxide film and a silicon nitride film. In addition, the etching method includes: a surface layer removal process including: etching the silicon oxide film at a first etching rate and removing a surface modification layer covering on the silicon nitride film; and an etching process including: etching the silicon oxide film at a second etching rate. The first etching rate is smaller than the second etching rate. In the etching method according to the present disclosure, through selectively etching the silicon oxide film, a substantial degradation of an etching selectivity ratio of SiO2/SiN caused by the surface modification layer on the wafer surface can be avoided.

  • Publication number: 20220342082
    Abstract: In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.

  • Publication number: 20220308984
    Abstract: Approaches presented herein enable fault detection. More specifically, implementation code of one or more functions is identified from source code. The implementation code of the one or more functions is converted to corresponding Abstract Syntax Trees (ASTs). The implementation code of the one or more functions is represented as a first plurality of sets of AST paths over the ASTs. Classification results for the one or more functions are generated with a classifier based on the first plurality of sets of AST paths for the implementation code of the one or more functions. Each of the classification results indicates a probability of having at least one fault in a corresponding function of the one or more functions. Fault detection results of the source code are generated based on the classification results.
