  • Patent number: 8872122
    Abstract: Described herein are embodiments of a method to control energy dose output from a laser-produced plasma extreme ultraviolet light system by adjusting timing of fired laser beam pulses. During stroboscopic firing, pulses are timed to lase droplets until a dose target of EUV has been achieved. Once accumulated EUV reaches the dose target, pulses are timed so as to not lase droplets during the remainder of the packet, and thereby prevent additional EUV light generation during those portions of the packet. In a continuous burst mode, pulses are timed to irradiate droplets until accumulated burst error meets or exceeds a threshold burst error. If accumulated burst error meets or exceeds the threshold burst error, a next pulse is timed to not irradiate a next droplet. Thus, the embodiments described herein manipulate pulse timing to obtain a constant desired dose target that can more precisely match downstream dosing requirements.

  • Patent number: 8872326
    Abstract: The mechanisms of forming a semiconductor device package described above provide a low-cost manufacturing process due to the relative simple process flow. By forming an interconnecting structure with a redistribution layer(s) to enable bonding of one or more dies underneath a package structure, the warpage of the overall package is greatly reduced. In addition, interconnecting structure is formed without using a molding compound, which reduces particle contamination. The reduction of warpage and particle contamination improves yield. Further, the semiconductor device package formed has low form factor with one or more dies fit underneath a space between a package structure and an interconnecting structure.

  • Patent number: 8872618
    Abstract: An unlocking method for an electronic device which has a plurality of light-sensors thereon and stores an application program therein first executes the application program when the electronic device works in a locking mode. When the application program is executed, the method continually computes a covering order of user's covering action performed on the light-sensors via the application program. Therefore, the method controls the electronic device to switch from the locking mode to an unlocking mode when the covering order of the covering action is matched with an unlocking condition.

  • Patent number: 8873606
    Abstract: Methods, systems, and apparatuses are described for reducing the latency in a transceiver. A transceiver includes a high latency communication channel and a low latency communication channel that is configured to be a bypass channel for the high latency communication channel. The low latency communication channel may be utilized when implementing the transceiver is used in low latency applications. By bypassing the high latency communication channel, the high latency that is introduced therein (due to the many stages of de-serialization used to reduce the data rate for digital processing) can be avoided. An increase in data rate is realized when the low latency communication channel is used to pass data. A delay-locked loop (DLL) may be used to phase align the transmitter clock of the transceiver with the receiver clock of the transceiver to compensate for a limited tolerance of phase offset between these clocks.

  • Patent number: 8873465
    Abstract: A baseband processing module of a base station includes a Turbo decoding module. The Turbo decoding module decodes a Turbo code word to produce one or more Media Access Control (MAC) packet(s) carried by the turbo decode word. Each MAC packet includes a MAC packet header and the MAC packet payload, which carries one or more Radio Link Control (RLC) Packet Data Units (PDUs). The Turbo decoding module decodes the MAC packet header to determine boundaries of the PDUs carried in the MAC packet payload. The Turbo decoding module decodes RLC PDU headers and RLC PDU payloads of the RLC PDUs. The Turbo decoding module writes the decoded MAC packet header, the decoded RLC PDU headers, and the decoded RLC PDU payloads to memory in a word-aligned format. The Turbo decoding module may also operate in various other Turbo decoding modes.
