  • Publication number: 20240170543
    Abstract: A method of fabricating a semiconductor structure includes selective use of a cladding layer during the fabrication process to provide critical dimension uniformity. The cladding layer can be formed before forming a recess in an active channel structure or can be formed after filling a recess in an active channel structure with dielectric material. These techniques can be used in semiconductor structures such as gate-all-around (GAA) transistor structures implemented in an integrated circuit.

  • Patent number: 11973985
    Abstract: Various schemes pertaining to pre-encoding processing of a video stream with motion compensated temporal filtering (MCTF) are described. An apparatus determines a filtering interval for a received raw video stream having pictures in a temporal sequence. The apparatus selects from the pictures a plurality of target pictures based on the filtering interval, as well as a group of reference pictures for each target picture to perform pixel-based MCTF, which generates a corresponding filtered picture for each target picture. The apparatus subsequently transmits the filtered pictures as well as non-target pictures to an encoder for encoding the video stream. Subpictures of natural images and screen content images are separately processed by the apparatus.

  • Patent number: 8829936
    Abstract: A probe card structure adaptable to different test apparatuses of different specifications includes a probe card adapted to a first specification, a reinforcement member adapted to a second specification and a specification conversion interface unit disposed between the probe card and the reinforcement member. The probe card without the specification conversion interface unit can be directly mounted on a test apparatus of the first specification by means of a reinforcement member of the first specification to carry out the test process. Alternatively, the specification conversion interface unit can be combined with the probe card to convert the probe card from the first specification to the second specification. Accordingly, the probe card of the second specification can be mounted on a test apparatus of the second specification by means of the reinforcement member of the second specification to carry out the test process.
