  • Patent number: 7274218
    Abstract: An integrated circuit includes a first and a second amplifier circuit (10, 20), which are in each case driven by an input signal (Vin) having a high and a low signal level and a reference signal (Vref) having a constant signal level and, on the output side (D11, D21) generate a first control signal (S1) and a second control signal (S2). The control signals (S1, S2) are generated independently of one another and are used to regulate a first controllable resistor (31) and a second controllable resistor (32) of a third amplifier circuit (30). Depending on the resistance value of the first and second controllable resistors (31, 32) of the third amplifier circuit, an output signal (Vout) that is amplified in comparison with the input signal (Vin) can be generated at an output terminal (A). The integrated circuit can be used as an input amplifier of an integrated semiconductor memory and permits an adaptive behavior of the input amplifier with regard to fluctuations of the average absolute input signal level.

  • Patent number: 7273638
    Abstract: A method of oxidizing a substrate having area of about 30,000 mm2 or more. The surface is preferably comprised of silicon-containing materials, such as silicon, silicon germanium, silicon carbide, silicon nitride, and metal suicides. A mixture of oxygen-bearing gas and diluent gas normally non-reactive to oxygen, such as Ne, Ar, Kr, Xe, and/or Rn are ionized to create a plasma having an electron density of at least about 1e12 cm?3 and containing ambient electrons having an average temperature greater than about 1 eV. The substrate surface is oxidized with energetic particles, comprising primarily atomic oxygen, created in the plasma to form an oxide film of substantially uniform thickness. The oxidation of the substrate takes place at a temperature below about 700° C., e.g., between about room temperature, 20° C., and about 500° C.

  • Patent number: 7274867
    Abstract: A system and method for determining the temperature of a semiconductor wafer at the time of thermal contact of the semiconductor wafer with a temperature sensing element. According to the invention, a temperature profile of the temperature sensing element is recorded from the time of thermal contact up to the time of thermal equilibrium between the semiconductor wafer and the temperature sensing element and the temperature of the semiconductor wafer at the time of thermal contact is determined on the basis of a time period between the time of thermal contact and the time of thermal equilibrium and the temperature TG of the semiconductor wafer reached at the time tG of thermal equilibrium is determined by back calculation with the aid of an equation derived from Newton's law of cooling.

  • Patent number: 7274755
    Abstract: Receiver for Receiving Data Frames. According to one aspect, a receiver for receiving data frames which contain information data includes a signal input. Further, the receiver includes a data frame separator circuit for separating the signaling data from the information data. A switching device connects the data present at current input to a data output. A channel decoding circuit decodes the data which is present and generates signals which indicate whether the decoding has been carried out correctly. When correct decoding has taken place, a control circuit buffers all data and outputs a signal to the switching device to connect the buffered information data to the channel decoding circuit. When the signal indicates the correct decoding is received, the control circuit outputs the decoded information data.
