  • Patent number: 11901245
    Abstract: A semiconductor package structure and a method for manufacturing the same are provided. The method includes: providing a package body includes a first semiconductor device, wherein the first semiconductor device includes a plurality of first electrical contacts disposed adjacent to an active surface of the first semiconductor device; measuring the actual positions of the first electrical contacts of the first semiconductor device; providing a plurality of second electrical contacts outside the first semiconductor device; and forming an interconnection structure based on the actual positions of the first electrical contacts of the first semiconductor device and the positions of the second electrical contacts satisfying a predetermined electrical performance criterion by a mask-less process, so as to connect the first electrical contacts and the second electrical contacts and maintain signal integrity during transmission.
    Type: Grant

  • Patent number: 8390732
    Abstract: One method of adjusting a focal length of a camera obtains a captured image of the camera by an application server, where a user can log onto the application server and decides if there is a need to adjust the focal length of the camera again. Another method obtains a captured image of the camera by an application server, determines if a quality of the captured image is acceptable by the application server, and sends the determination results to a mobile device. The focal length of the camera is adjusted again by checking the determination result on the mobile device.
