  • Publication number: 20210066490
    Abstract: The current disclosure describes techniques for forming a gate-all-around device where semiconductor layers are released by etching out the buffer layers that are vertically stacked between semiconductor layers in an alternating manner. The buffer layers stacked at different vertical levels include different material compositions, which bring about different etch rates with respect to an etchant that is used to remove at least partially the buffer layers to release the semiconductor layers.

  • Publication number: 20210053192
    Abstract: The present invention relates to a suction device, including a body. A cavity is disposed in the body. The cavity has a closed end face and an open end face. The open end face forms an end face to suck a workpiece. A tangential nozzle is disposed on a sidewall surface of the cavity. An external fluid enters the cavity through the tangential nozzle along a tangential direction of the cavity. A suction hole is disposed on the closed end face. The suction hole is connected to a suction unit. The suction unit sucks the fluid in the cavity through the suction hole. The suction device can suck a workpiece by using both a rotational flow negative pressure and a negative suction pressure of a fluid in the cavity, and therefore can suppress impact of a workpiece surface on a suction force and generate a larger suction force.

  • Patent number: 10810374
    Abstract: Described is a system that matches a query with a set of sentences. When a query is received, the system may extract features from the query including one or more words as tokens and retrieve a set of candidate sentences as potential results for the query. For example, the query may be in the form of a question, and the candidate sentences may be alternative phrasings of the query that potentially match the user's search intent. The relevant set of candidate sentences may be determined based on using multiple relevancy scores and the system may rank the candidates according to an overall or aggregate score. Accordingly, the set of results to a query may be provided by recognizing the sentence as a whole and, for example when the query is a question, the interrogative intent of the query.
