  • Publication number: 20170236811
    Abstract: Selective transfer of dies including semiconductor devices to a target substrate can be performed employing local laser irradiation. Coining of at least one set of solder material portions can be employed to provide a planar surface-to-surface contact and to facilitate bonding of adjoining pairs of bond structures. Laser irradiation on the solder material portions can be employed to sequentially bond selected pairs of mated bonding structures, while preventing bonding of devices not to be transferred to the target substrate. Additional laser irradiation can be employed to selectively detach bonded devices, while not detaching devices that are not bonded to the target substrate. The transferred devices can be pressed against the target substrate during a second reflow process so that the top surfaces of the transferred devices can be coplanar. Wetting layers of different sizes can be employed to provide a trapezoidal vertical cross-sectional profile for reflowed solder material portions.

  • Patent number: 9693175
    Abstract: A wireless communication device generates and transmits wireless broadband signals at a power level that is below a spurious emissions mask such that the transmitted wireless broadband signals occupy a designated frequency spectrum band. A bandwidth of the wireless broadband signals may occupy approximately 800 MHz within a range of 0 Hz to 1 GHz. The transmit power utilized for transmitting the wireless broadband signals may be spread over a bandwidth of approximately 300 MHz within the 800 MHz bandwidth. The spreading results in a power spectral density of the transmitted wireless broadband signals approximating thermal noise at a distance of approximately 3 meters. Available channels within the designated frequency spectrum band may be sensed for the transmission of the wireless broadband signals. A plurality of the sensed available channels may be aggregated for the transmission of the wireless broadband signals.
