  • Publication number: 20240105782
    Abstract: A monocrystalline SiC substrate comprising a first surface and a second surface. The first surface comprises pinning regions and a device region. Each of the pinning regions is configured to provide a potential well which is capable to attract dislocations from a region surrounding said pinning region. The device region is configured to provide a part of the monocrystalline SiC substrate for manufacturing a semiconductor device. The device region is surrounded by the pinning regions, and a density of dislocations in a central portion of the device region is smaller than a density of dislocations in an edge of the device region due to the pinning regions. The pinning regions surrounding the device region attracts dislocations of the device region into the edge portion, so that the density of dislocations in the central portion is reduced. A yield of the semiconductor devices is improved.

  • Publication number: 20210392349
    Abstract: A client device may receive encoded data of a first video frame from a server over a network, and decode the encoded data to obtain the first frame based at least in part on one or more second frames of a second resolution that are stored in a reference frame buffer of the client device. In response to determining that the first resolution is lower than the second resolution, the client device may or may not resize the first frame from the first resolution to the second resolution and store the first frame of the first resolution and/or the resized first frame of the second resolution in the reference frame buffer, depending on which coding design that the client device employs. The client device may display the reconstructed frame to a user.
