    摘要: Cyclic deposit and etch (CDE) selective epitaxial growth employs an etch chemistry employing a combination of hydrogen chloride and a germanium-containing gas to provide selective deposition of a silicon germanium alloy at temperatures lower than 625° C. High strain epitaxial silicon germanium alloys having a germanium concentration greater than 35 atomic percent in a temperature range between 400° C. and 550° C. A high order silane having a formula of SinH2n+2, in which n is an integer greater than 3, in combination with a germanium-containing precursor gas is employed to deposit the silicon germanium alloy with thickness uniformity and at a high deposition rate during each deposition step in this temperature range. Presence of the germanium-containing gas in the etch chemistry enhances the etch rate of the deposited silicon germanium alloy material during the etch step.

    摘要: In accordance with some embodiments, in a time division duplex system, the transmission direction may be changed dynamically, for example in response to instantaneous traffic conditions. Particularly in some embodiments an eNodeB or base station may, in response to instantaneous traffic conditions, change the direction of transmission in certain subframes. In some embodiments this can be done in a way which is backwards compatible with prior generations of Long-Term Evolution (LTE) radio systems.

    摘要: Technology for synchronization of uplink transmission with multiple timing advances in a wireless communication environment is disclosed. Additional resource allocation messages for additional timing advances are addressed to a user equipment specific search space. A number of band decodes needed to find a resource allocation message used to access an additional timing advance can be reduced by padding the resource allocation message. A number of blind decodes used to find the resource allocation message can also be reduced by restricting the control channel candidates in which the resource avocation can be embedded in terms of the control channel element aggregation level, or levels, associated with acceptable control channel candidates.

    摘要: A method of depositing an epitaxial layer that includes chemically cleaning the deposition surface of a semiconductor substrate and treating the deposition surface of the semiconductor substrate with a hydrogen containing gas at a pre-bake temperature. The hydrogen containing gas treatment may be conducted in an epitaxial deposition chamber. The hydrogen containing gas removes oxygen-containing material from the deposition surface of the semiconductor substrate. The deposition surface of the semiconductor substrate may then be treated with a gas flow comprised of at least one of hydrochloric acid (HCl), germane (GeH4), and dichlorosilane (H2SiCl2) that is introduced to the epitaxial deposition chamber as temperature is decreased from the pre-bake temperature to an epitaxial deposition temperature. At least one source gas may be applied to the deposition surface for epitaxial deposition of a material layer.

    摘要: A method for transmitting an uplink sounding reference signal includes indexing Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols within a single radio frame for transmitting a Sounding Reference Signal (SRS) as a number k, and calculating a value of nSRS according to number k and an index number of the radio frames for transmitting the SRS, determining an index number of a frequency-domain start sub-carrier mapped from time-domain SRS symbol with nSRS, and transmitting the SRS through the sub-carrier with the determined index number determined. Before transmitting the SRS, the start frequency position for SRS should be changed according to the specific frequency-hop pattern to guarantee that the UE may uniformly sound the entire SRS frequency-hop bandwidth after multiple soundings.
