  • Patent number: 11961775
    Abstract: In one example, a semiconductor device can comprise a substrate, a device stack, first and second internal interconnects, and an encapsulant. The substrate can comprise a first and second substrate sides opposite each other, a substrate outer sidewall between the first substrate side and the second substrate side, and a substrate inner sidewall defining a cavity between the first substrate side and the second substrate side. The device stack can be in the cavity and can comprise a first electronic device, and a second electronic device stacked on the first electronic device. The first internal interconnect can be coupled to the substrate and the device stack. The encapsulant can cover the substrate inner sidewall and the device stack and can fill the cavity. Other examples and related methods are disclosed herein.

  • Publication number: 20120084294
    Abstract: Provided is a method and apparatus for providing an indexing service in a portable terminal. The method includes recognizing at least one data selected by a user from a first file provided through a text viewer of the portable terminal and extracting absolute locations of the recognized data in the first file, storing the extracted locations of the data and arranging the data in a predetermined order to create a first sub file related to the first file, and indexing the first file to allow a search in the first file based on particular data by displaying the locations stored for the respective data arranged in the created first sub file. The first sub file is further linked to data from other files according to the data selected by a user so that a user can determine location of a particular data.
