  • Patent number: 9185713
    Abstract: Embodiments of the present invention may provide an apparatus and a method for transmitting and receiving a random access channel (RACH) in a single carrier-frequency division multiple access (SC-FDMA) system. A frequency domain RACH signal may be mapped to a localized sub-frequency band of an entire frequency band available to the SC-FDMA system. A guard band including at least one sub carrier may be allocated between the RACH signal band and other channel signal bands. A guard time may be allocated between the RACE signal and other channel signals in the time domain. The RACH signal may include a short message including information related to a mobile station. The RACE signal may be detected in a frequency based method, a time based method or a sliding matched filter based method. Receiver complexity can be decreased if the RACH signal includes a CAZAC code sequence for a preamble. In such a case, a receive delay may be simply calculated and then adjusted more accurately.

  • Patent number: 9177932
    Abstract: Disclosed is a semiconductor device having overlapped via apertures formed in an encapsulant to outwardly expose solder balls. When different types of semiconductor devices are electrically connected to the solder balls through the overlapped via apertures, flux or solder paste is unlikely to contact sidewall portions of the overlapped via apertures. Therefore, different types of semiconductor devices can be mounted with improved efficiency.

  • Patent number: 8525318
    Abstract: Disclosed are a semiconductor device capable of efficiently radiating heat of a semiconductor die and a method of fabricating the same. The semiconductor device efficiently radiates the heat by preventing an encapsulant from reaching the semiconductor die by an encapsulant dam so that an upper surface of the semiconductor die is exposed out of the encapsulant. In addition, the semiconductor device is configured to expose a pre-solder ball or a conductive pattern of a substrate through a via of the encapsulant. Therefore, electrical connection between the pre-solder ball and a solder ball of another semiconductor device stacked thereon is easily achieved.
