  • Patent number: 7214568
    Abstract: A semiconductor device includes an IC die configured to reduce post-fabrication damage to the device. The IC die is formed such that at least a portion of one or more perimeter edges of the die are beveled by an etching process. The semiconductor device may include a plurality of IC dies, at least one of the IC dies being separated from the semiconductor device by forming one or more v-shaped grooves in an upper surface of the device, the v-shaped grooves defining perimeter edges of the at least one IC die. A back surface of the semiconductor device is removed until at least a portion of the v-shaped grooves are exposed. When the IC die is separated from the semiconductor device in this manner, a sidewall of each of the v-shaped grooves forms a beveled perimeter edge of the separated IC die.

  • Publication number: 20060225100
    Abstract: A signal distribution and control system where signals are distributed and control signals transmitted via a single coaxial cable. Integrated Receiver/Decoder (IRD) units communicate with a Frequency Translation Module (FTM) for construction of a custom data signal for delivery to all IRDs coupled to a given FTM. The commands sent by the IRDs to control the FTM inform the FTM which signals are of interest and should be placed on the custom data signal, also called the combined IRD channels. Previously installed IRDs that cannot generate the new commands are still supported in the system via legacy ports in the multiswitch.

  • Publication number: 20020131412
    Abstract: Efficient techniques for processing multicast requests in a switch system are disclosed. The efficient techniques lead to substantial reduction in switch system bandwidth consumption while processing multicast requests. In one embodiment, a multicast queue is used to hold multicast blocks of data (e.g., cells) that are to be switched, and duplication of the blocks of data for delivery to multiple destinations (e.g., ports) is performed by a switch device (e.g., crossbar switch) as opposed to storage queues or repeated transfers from storage queues to the switch device.
