  • Systems for data transmission
    Patent number: 7027522
    Abstract: A differential data transmission system that transmits encoded data symbols as differential signals. A signal for transmitting symbols on a set of at least three parallel channels, each channel having a first terminal, P1 to PN, and each channel having a second terminal connected to a common node Z. The signal comprising for each symbol an active signal on two of those channels and an inactive signal on the remaining channel or channels, the symbols being distinguishable by which two of the channels have the active signals.
    Type: Grant
    Filed: July 25, 2001
    Date of Patent: April 11, 2006
    Assignee: Texas Instruments Incorporated

  • Method for maintaining the buffer capacity of siliceous chemical-mechanical silicon polishing slurries
    Patent number: 6028006
    Abstract: A method for maintaining the buffer capacity of a polishing slurry during chemical-mechanical wafer polishing, the method comprising circulating the polishing slurry in a chemical-mechanical wafer polishing apparatus, monitoring the pH of the polishing slurry, combining an agent into the polishing slurry to adjust the pH of the polishing slurry and maintaining the pH of the polishing slurry within a predetermined range, thereby maintaining the buffer capacity of the polishing slurry.
