  • Publication number: 20240129632
    Abstract: A wafer position status inspection apparatus includes a wafer transportation device, a robotic arm rotatably mounted on the wafer transportation device, an image capture device arranged on the robotic arm, a light flashing device arranged at one side of the image capture device, and a status inspection section in information connection with the image capture device. An image capturing direction of the image capture device is set consistent with a gripping direction of the robotic arm, and a light projecting direction of the light flashing device is consistent with the image capturing direction. The light flashing device projects light on a wafer to generate a light-reflecting contour, which is captured by the image capture device to form a wafer contour image based on which the status inspection section acquires a wafer deposition status to identify various wafer statuses including incline, overlap, absence, and warp.

  • Publication number: 20220036323
    Abstract: A computer-implemented system and method uses a processor of a device of an expiring virtual currency (EVC) wallet user. An EVC transaction is retrieved that is associated with a blockchain and addressed to an address associated with the EVC wallet. The EVC transaction comprises an expiration date for the EVCs, as part of virtual currency user rules (VCURs). If the expiration date of the EVCs has passed, the method automatically, and without user intervention, transfers the EVCs to a transferee designated in the VCURs.
