  • Patent number: 11923429
    Abstract: A semiconductor device and method for forming the semiconductor device are provided. In some embodiments, a semiconductor substrate comprises a device region. An isolation structure extends laterally in a closed path to demarcate the device region. A first source/drain region and a second source/drain region are in the device region and laterally spaced. A sidewall of the first source/drain region directly contacts the isolation structure at a first isolation structure sidewall, and remaining sidewalls of the first source/drain region are spaced from the isolation structure. A selectively-conductive channel is in the device region, and extends laterally from the first source/drain region to the second source/drain region. A plate comprises a central portion and a first peripheral portion. The central portion overlies the selectively-conductive channel, and the first peripheral portion protrudes from the central portion towards the first isolation structure sidewall.

  • Patent number: 11645375
    Abstract: Embodiments of the present disclosure relate to methods, systems and computer program products for authorization of resource access. According to the method, a first token is assigned by one or more processing units to authorize a client to access at least one protected resource of a resource owner. The first token depends on an access session with the client. A second token associated with at least one long-term protected resource of the resource owner is assigned by one or more processing units to the client based on the assigning of the first token. The second token is independent from the access session. In response to receiving a request including the second token from the client, the at least one long-term protected resource is provided by one or more processing units to the client. In other embodiments, a further method and corresponding systems and computer program products are disclosed.

  • Publication number: 20220339679
    Abstract: A multifunctional cleaning pen and a method for cleaning an object are disclosed. The cleaning pen includes a main body, a pen head assembly, an air supply assembly, and a control assembly. The pen head assembly can lift or adsorb a target object for examination onto a platform by a vacuum through the pen, avoiding physical contact with the object by hard tools. The air supply assembly is inside the main body and the control assembly is on a surface of the main body. When the object is in place, it can be cleaned by a jet of air forced out of the pen, and also by a vibrated alcohol wiper on the pen. By utilizing the multifunctional cleaning pen, a cleaning effect in relation to fragile and delicate materials such as camera, mobile phone speaker, and card tray, is improved.
