Publication number: 20240105496Abstract: The present invention provides a substrate supporting apparatus having a spin chuck and a plurality of locating pins. The spin chuck configured to support and rotate a substrate has a supporting surface. The locating pins are disposed at the periphery of the supporting surface for limiting the substrate horizontal displacement. The supporting surface defines a first annular region. The first annular region is divided into a plurality of pin regions and a plurality of non-pin regions. The pin regions and the non-pin regions are arranged alternatively in a circumferential direction of the first annular region. Each of the pin regions is corresponding to one locating pin. A plurality of Bernoulli holes are set in the first annular region and is configured as an uneven structure in the first annular region so as to supply stronger gas flow in the pin regions than in the non-pin regions.Type: ApplicationFiled: December 16, 2020Publication date: March 28, 2024Applicant: ACM RESEARCH (SHANGHAI), INC.Inventors: Hui Wang, Feng Liu, Xiaofeng Tao, Shena Jia, Fuping Chen, Haibo Hu, Yang Liu

Patent number: 11615099Abstract: A method and an apparatus for sending key-value pair data are provided, and a method and an apparatus for collecting key-value pair data are provided. In the method, first target key-value pair data is perturbed as first perturbed key-value pair data, so that a data collector can determine, based on a value a or b of a first value in the first perturbed key-value pair data, whether to include the entire first perturbed key-value pair data into the statistical result in a process of generating the statistical result. In this way, an association between a value and a key in the key-value pair data is reserved in the first perturbed key-value pair data, which improves availability of the first perturbed key-value pair data. That is, a statistical result generated by the data collector based on the first perturbed key-value pair data is closer to a statistical result generated based on original user key-value pair data.Type: GrantFiled: December 1, 2020Date of Patent: March 28, 2023Assignees: Huawei Technologies Co., Ltd., The Hong Kong Polytechnic UniversityInventors: Qingqing Ye, Haibo Hu

Publication number: 20220207117Abstract: In a data theft prevention method, a data processing apparatus obtains target data, inputs the target data into a recognition model for recognition processing to obtain a first label, where the first label is a label to which the target data belongs. The recognition processing includes: performing, by the recognition model, feature extraction on the target data to obtain a first feature vector; and obtaining, by the recognition model, the first label through prediction based on the first feature vector; and outputs a target label when determining that a second feature vector exists. The second feature vector is a feature vector whose distance from the first feature vector is less than a first threshold. A second label obtained through prediction by using the recognition model is different from the first label and the target label is a label obtained by performing perturbation processing on the first label.Type: ApplicationFiled: March 18, 2022Publication date: June 30, 2022Applicant: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Haibo HU, Huadi ZHENG, Qingqing YE, Chengfang FANG, JIE SHI
