Patent number: 7708830Abstract: A method for the production of a silicon single crystal by pulling the single crystal, according to the Czochralski method, from a melt which is held in a rotating crucible, the single crystal growing at a growth front, heat being deliberately supplied to the center of the growth front by a heat flux directed at the growth front. The method produces a silicon single crystal with an oxygen content of from 4*1017 cm?3 to 7.2*1017 cm?3 and a radial concentration change for boron or phosphorus of less than 5%, which has no agglomerated self-point defects. Semiconductor wafers are separated from the single crystal.

Patent number: 7366754Abstract: A method and an apparatus using a system level clocking scheme to remove jitter from multi-media packets distributed over an asynchronous network, in particular an Ethernet network. The present invention overcomes the problems associated with jitter introduced in an Ethernet network by using various time stamps to synchronize a client device clock to a headend clock and to control the data flow in the client device to match the rate that the data is received by a broadband receiver coupled to the headend. A first time stamp is prepended to the transport packets when the packets are received from the headend. A second time stamp is placed in the data frame when the data frame is placed on the network. A third time stamp is placed in the data frame when the data frame is received from the network. The second and third time stamps are used for clock synchronization and the first time stamp is used for data flow control.Type: GrantFiled: June 29, 2001Date of Patent: April 29, 2008Assignee: Thomson LicensingInventors: Daniel Thomas Wetzel, Anh Quang Nguyen

Patent number: 6944878Abstract: A method and apparatus for ensuring a correct satellite signal connection. Specifically, a user selects a satellite signal via an integrated receiver/decoder (IRD) from at least one satellite, and the IRD sends a command signal to a selector switch to acquire and lock onto said satellite signal. The IRD repeats transmission of the command signal to the selector switch once the IRD has acquired and locked onto said information signal. Thus, in the event that the selector switch failed to switch to a low noise block converter (LNB) corresponding to the initial command signal, then the repeated command signal helps to ensure that the selector switch switches to the LNB corresponding with the latest command signal sent by the IRD.Type: GrantFiled: December 30, 1999Date of Patent: September 13, 2005Assignee: Thomson Licensing S.A.Inventors: Daniel Thomas Wetzel, Terry Wayne Lockridge, Michael F.

Patent number: 6143646Abstract: A method for forming a dual inlaid contact structure (damascene) begins by etching dual inlaid contact structures (32, 34, and 36). Masking layers (28) are (228) and the deposition of low-K dielectric material 26 is used to selectively form low-K regions (30) only in critical areas where low-K dielectric material is absolutely needed. Other portions of the wafer remain covered with conventional oxide (24) so that adverse impacts of low-K dielectric material is minimized. Conductive material (38, 40, and 42) is then formed to complete dual inlaid contact structures whereby low-K dielectric plugs (30) reduce cross talk and capacitance within the final structure.Type: GrantFiled: June 3, 1997Date of Patent: November 7, 2000Assignee: Motorola Inc.Inventor: Jeffrey Thomas Wetzel

Patent number: 5880018Abstract: An interconnect structure having a dielectric layer with low dielectric constant is formed within an integrated circuit. In one embodiment of the invention, portions of a silicon dioxide layer (18) lying adjacent to a conductive interconnect (21) are removed to expose portions of a silicon nitride etch stop layer (16). A dielectric layer (22) having a low dielectric constant is then formed overlying the conductive interconnect (21) and the exposed portions of the silicon nitride etch stop layer (16). A portion of the dielectric layer (22) is then removed to expose the top surface of the conductive interconnect (21) to leave portions of the dielectric layer (22) between adjacent conductive interconnects (21). The resulting interconnect structure has reduced cross-talk between conductive interconnects (21) while avoiding prior art disadvantages of reduced thermal dissipation and increased mechanical stress.Type: GrantFiled: October 7, 1996Date of Patent: March 9, 1999Assignee: Motorola Inc.Inventors: Bruce Allen Boeck, Jeff Thomas Wetzel, Terry Grant Sparks
