  • Patent number: 9503238
    Abstract: Methods and apparatus for receiving a first control channel and a second control channel in a wireless communication system are provided. Control information for receiving the second control channel from a base station is received through higher layer signaling. A second control channel resource is determined from an entire control channel resource based on the control information. A first control channel resource is determined from the entire control channel resource according to the second control channel resource.

  • Patent number: 7682985
    Abstract: A method for etching a stack with at least one silicon germanium layer over a substrate in a processing chamber is provided. A silicon germanium etch is provided. An etchant gas is provided into the processing chamber, wherein the etchant gas comprises HBr, an inert diluent, and at least one of O2 and N2. The substrate is cooled to a temperature below 40° C. The etching gas is transformed to a plasma to etch the silicon germanium layer.

  • Patent number: 6923920
    Abstract: A method for etching a wafer having a pattern of photoresist material thereon is disclosed. The method includes curing the photoresist material with a bromine containing plasma. Then a main etch of the wafer is carried out. A method for curing a pattern of photoresist material on a wafer is also disclosed. The curing method includes providing a bromine containing plasma and exposing the photoresist material to the plasma, such that a layer of the wafer below the photoresist material is not etched through. A composition of a plasma for curing a photoresist material on a wafer in a high density plasma processing device includes bromine.

  • Patent number: 6770214
    Abstract: A method of reducing aluminum fluoride deposits in a plasma etch reactor. The deposits can be reduced during a cleaning step wherein the cleaning gas includes BCl3 energized into a plasma such that dissociated and undissociated BCl3 are formed and the undissociated BCl3 reacts with aluminum fluoride deposits and forms volatile products which are removed from the chamber. The introduction of Cl2 into the cleaning gas allows control of the degree of BCl3 dissociation. The deposits can also be reduced during etching of an aluminum layer by controlling the amount of fluorocarbon used in the main etch and adding BCl3 during the overetch. The cleaning step may be performed without a substrate in the chamber and may be followed by a conditioning step.
