  • Publication number: 20210358867
    Abstract: Provided is a method suitable for efficiently manufacturing a semiconductor device while preventing warpage of the wafer laminate in manufacturing a semiconductor device in which semiconductor elements are multilayered through laminating wafers in which the semiconductor elements are fabricated. The method includes at least: preparing a plurality of first wafer laminates each having a laminate configuration including a first and second wafers each having an element forming surface and a back surface opposite from the element forming surface, the laminate configuration wherein the element forming surface sides of the first and second wafers are bonded to each other; thinning the first wafer of the first wafer laminate to form a first wafer laminate having the thinned first wafer; and bonding the thinned first wafer sides of two first wafer laminates having undergone the thinning to each other to form a second wafer laminate.

  • Patent number: 9195898
    Abstract: Implementations relate to systems and methods for real-time image recognition and mobile visual searching. A mobile device, such as a cellular phone, acquires an image and pre-processes the acquired image to generate a visual search query based on objects detected in the acquired image. The visual search query includes the acquired image or a query image extracted therefrom and metadata associated with the detected objects. The mobile device wirelessly communicates the visual search query to a remote server, and in response to the visual search query, the remote server recognizes an object in the query image based on the associated metadata. The remote server then generates information content based on the recognized object and communicates the information content to the mobile device to be presented via the mobile device.

  • Publication number: 20100262953
    Abstract: An application management server may automatically disable applications or widgets that are incompatible with a user's computing device, and automatically re-enable such applications or widgets when the user's computing device is compatible. Auto-disabled applications may be tracked in memory of a server by setting an auto-disabled status indication associated with the disabled application or widget. If an auto-disabled application or widget is upgraded or the user swaps computing devices, thereby resolving the incompatibility, the server may auto-enable such applications and widgets that were previously auto-disabled so that they may be downloaded to or used from the user's computing device. The server may recognize when a software upgrade resolves an incompatibility and prompt a computing device to initiate a synchronization process to receive the auto-enabled application or widget to the computing device or to the user's application server-based locker or profile.
